About this paper
Sir Adnan's 'PMS 2026 –GK BOOKLET' one-liner booklet (5 pp, header 'ONE-LINER (PPSC/FPSC NEW TREND 2025-26)') from the monster-data 'PMS SCREENING 2026 GK UPDATED' pack. 49 of 50 printed items published (1 dropped: printed Q32, an exact internal duplicate of Q17, 'Unit of frequency? Hertz'). Two booklet answers are corrected to the standard SI answer and flagged in keyFlag: printed Q10 (magnetic field intensity → ampere per metre, not tesla) and printed Q42 (electric flux → volt-metre, not weber).

Correct Answer: Isobar
An isobar joins points of equal atmospheric pressure on a weather map.
Correct Answer: Isotherm
An isotherm joins points of equal temperature.
Correct Answer: Isohyet
An isohyet joins points of equal rainfall (precipitation).
Correct Answer: Contour line
A contour line (also called an isohypse) joins points of equal elevation above a datum such as sea level.
Correct Answer: Isohume
An isohume joins points of equal humidity.
Correct Answer: Isohaline
An isohaline joins points of equal salinity (salt content).
Correct Answer: Isotach
An isotach joins points of equal wind speed.
Correct Answer: Equipotential line
An equipotential line joins points of equal electric potential; no work is done moving a charge along it.
Correct Answer: Isotach
An isotach joins points of equal flow velocity (the same term as for equal wind speed).
Correct Answer: Isogal
On gravity maps, lines of equal gravitational acceleration are called isogals.
Correct Answer: Isobar
An isobar joins points of equal pressure, including on a vertical cross-section of the atmosphere.
Correct Answer: Isopotential line
The booklet's term for lines of equal (magnetic) potential is the isopotential line, the magnetic counterpart of the electric equipotential line.
Correct Answer: Isohyet
An isohyet joins points of equal rainfall, including equal rainfall intensity on a rainfall map.
Correct Answer: Isobar
Sea-level pressure charts draw isobars, lines of equal pressure reduced to sea level.

17 solved MCQs shown directly below
Correct Answer: Isotope
Isotopes of an element have the same number of protons but different numbers of neutrons, so their mass numbers differ.
Correct Answer: Isotone
Isotones have the same neutron number but different proton numbers, so they are different elements.
Correct Answer: Carbon
Carbon has 6 protons, so its atomic number is 6.
Correct Answer: Hydrogen
Hydrogen has 1 proton, so its atomic number is 1.
Correct Answer: Protium, Deuterium, Tritium
Hydrogen's three isotopes are protium (¹H, no neutron), deuterium (²H, one neutron) and tritium (³H, two neutrons).
Correct Answer: 8
Carbon has 6 protons, so neutrons = mass number − protons = 14 − 6 = 8.
Correct Answer: U-235, U-238
Reactor fuel is chiefly uranium containing the fissile isotope U-235 together with the fertile isotope U-238.
Correct Answer: Isobar
Isobars are nuclides of different elements with the same mass number (same total of protons + neutrons) but different proton numbers.
Correct Answer: Isotone
Nuclides with the same neutron number are isotones, whatever their proton number.
Correct Answer: Cl-35, Cl-37
Naturally occurring chlorine is mainly Cl-35 (about 75%) and Cl-37 (about 25%).
Correct Answer: O-16, O-17, O-18
Oxygen's stable isotopes are O-16 (by far the commonest), O-17 and O-18.
Correct Answer: C-12, C-13, C-14
Carbon's isotopes are C-12 (the standard, about 99%), C-13 and the radioactive C-14 used in radiocarbon dating.
Correct Answer: 6
Carbon's atomic number is 6, so every carbon atom, including carbon-12, has 6 protons.
Correct Answer: 6
Neutrons = mass number − protons = 12 − 6 = 6.
Correct Answer: 7
Nitrogen's atomic number is 7, so nitrogen-14 has 7 protons.
Correct Answer: 7
Neutrons = mass number − protons = 14 − 7 = 7.
Correct Answer: Isoelectronic
Isoelectronic species have the same number of electrons (and usually the same electron configuration) but different proton numbers.

Correct Answer: Ampere
Electric current is measured in amperes (A).
Correct Answer: Ohm
Electric resistance is measured in ohms (Ω).
Correct Answer: Volt
Electric potential (potential difference) is measured in volts (V).
Correct Answer: Ampere per metre
Magnetic field intensity H is measured in amperes per metre (A/m). Tesla is the unit of magnetic flux density B, a different quantity.
Correct Answer: Newton
Force is measured in newtons (N).
Correct Answer: Pascal
Pressure is measured in pascals (Pa), one newton per square metre.
Correct Answer: Joule
Energy is measured in joules (J).
Correct Answer: Hertz
Frequency is measured in hertz (Hz), cycles per second.
Correct Answer: Joule
Work, like energy, is measured in joules (J).
Correct Answer: Watt
Power, the rate of doing work, is measured in watts (W), one joule per second.
Correct Answer: Coulomb
Electric charge is measured in coulombs (C).
Correct Answer: Farad
Capacitance is measured in farads (F).
Correct Answer: Henry
Inductance is measured in henries (H).
Correct Answer: Candela
Luminous intensity is measured in candelas (cd).
Correct Answer: Kelvin
The SI unit of temperature is the kelvin (K); Celsius and Fahrenheit are other temperature scales, not the SI unit.
Correct Answer: Metre
Wavelength is a length, so it is measured in metres (m).
Correct Answer: Volt-metre
Electric flux is electric field × area, so its SI unit is (volt per metre) × (square metre) = volt-metre (V·m). Weber is the unit of magnetic flux, not electric flux.
Correct Answer: Tesla
Magnetic flux density (magnetic induction) B is measured in teslas (T), one weber per square metre.
Source & verification
Built by GK360 from verified bank questions — every answer rechecked before publishing. Where the source printed no options, the answer options were prepared by GK360; the questions and correct answers are the verified originals.
Questions
No. It is Sir Adnan's 'PMS 2026 –GK BOOKLET' one-liner booklet from the monster-data 'PMS SCREENING 2026 GK UPDATED' pack, published as paperType 'practice', never as a past paper. The year 2026 is the booklet's label, not a claimed exam session.
The booklet prints 50 items, but printed Q32 ('Unit of frequency?') exactly repeats printed Q17 ('Unit of frequency? Hertz'), so the duplicate was dropped and only the first occurrence is published.
Printed Q10 and Q42 are corrected to the standard SI answers and flagged in keyFlag: magnetic field intensity (H) is measured in amperes per metre (tesla is magnetic flux density), and electric flux is measured in volt-metres (weber is magnetic flux).
SI units for electricity, magnetism, force, pressure, energy, power and temperature; isopleth lines (isobar, isotherm, isohyet, isotach, isohume, isohaline, isogal, contour and equipotential lines); and isotopes and proton/neutron counts for hydrogen, carbon, oxygen, chlorine, nitrogen and uranium.
