Q1.The bending of light as it passes from one medium to another is:
Show answer & explanation
Answer: D — Refraction
Refraction is caused by a change in light’s speed.
-
Q2.A current of 2 A flows through a 2 Ω resistor. What is the potential difference across it?
Show answer & explanation
Answer: C — 4 V
Ohm’s law: V = IR = 2 × 2 = 4 V.
-
Q3.Acceleration due to gravity on Earth’s surface is about:
Show answer & explanation
Answer: A — 9.8 m/s²
g ≈ 9.8 m/s².
-
Q4.Find the power dissipated when 0.5 A flows through a 5 Ω resistor.
Show answer & explanation
Answer: A — 1.25 W
P = I²R = 0.5² × 5 = 1.25 W.
-
Q5.Which law states that every action has an equal and opposite reaction?
Show answer & explanation
Answer: A — Newton’s third law
Newton’s third law.
-
Q6.A body starts at 5 m/s and accelerates uniformly at 1 m/s² for 3 s. Find its final velocity.
Show answer & explanation
Answer: A — 8 m/s
v = u + at = 5 + 1×3 = 8 m/s.
-
Q7.The upthrust on a body immersed in a fluid equals the weight of fluid displaced. This is:
Show answer & explanation
Answer: C — Archimedes’ principle
Archimedes’ principle.
-
Q8.What force is needed to accelerate a 14 kg mass at 9 m/s²?
Show answer & explanation
Answer: C — 126 N
F = ma = 14 × 9 = 126 N.
-
Q9.The phenomenon responsible for the blue colour of the sky is:
Show answer & explanation
Answer: D — Rayleigh scattering
Shorter (blue) wavelengths are scattered more by air molecules.
-
Q10.A body starts at 6 m/s and accelerates uniformly at 4 m/s² for 9 s. Find its final velocity.
Show answer & explanation
Answer: C — 42 m/s
v = u + at = 6 + 4×9 = 42 m/s.
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.
