Q1.The SI unit of force is the:
Show answer & explanation
Answer: B — Newton
1 newton = 1 kg·m/s².
-
Q2.A body starts at 7 m/s and accelerates uniformly at 2 m/s² for 5 s. Find its final velocity.
Show answer & explanation
Answer: B — 17 m/s
v = u + at = 7 + 2×5 = 17 m/s.
-
Q3.The unit of electrical resistance is the:
Show answer & explanation
Answer: B — Ohm
Resistance is measured in ohms (Ω).
-
Q4.A body with initial velocity 0 m/s accelerates at 2 m/s² for 4 s. Find the distance covered.
Show answer & explanation
Answer: D — 16 m
s = ut + ½at² = 0×4 + ½×2×4² = 16 m.
-
Q5.The frequency of a wave is measured in:
Show answer & explanation
Answer: D — Hertz
1 hertz = 1 cycle per second.
-
Q6.What force is needed to accelerate a 39 kg mass at 3 m/s²?
Show answer & explanation
Answer: B — 117 N
F = ma = 39 × 3 = 117 N.
-
Q7.The device that converts mechanical energy into electrical energy is a:
Show answer & explanation
Answer: C — Generator
A generator uses electromagnetic induction.
-
Q8.A current of 0.5 A flows through a 2 Ω resistor. What is the potential difference across it?
Show answer & explanation
Answer: C — 1 V
Ohm’s law: V = IR = 0.5 × 2 = 1 V.
-
Q9.Which particle has no electric charge?
Show answer & explanation
Answer: C — Neutron
Neutrons are electrically neutral.
-
Q10.Find the power dissipated when 3 A flows through a 20 Ω resistor.
Show answer & explanation
Answer: B — 180 W
P = I²R = 3² × 20 = 180 W.
How to approach physics questions
Write the formula before substituting and keep SI units throughout. Most numerical questions use one of: v = u + at, s = ut + ½at², F = ma, KE = ½mv², V = IR, P = I²R.
