  1. Q1.The phenomenon responsible for the blue colour of the sky is:

    Show answer & explanation

    Answer: B — Rayleigh scattering

    Shorter (blue) wavelengths are scattered more by air molecules.

  2. Q2.A body starts at 9 m/s and accelerates uniformly at 3 m/s² for 8 s. Find its final velocity.

    Show answer & explanation

    Answer: D — 33 m/s

    v = u + at = 9 + 3×8 = 33 m/s.

  3. Q3.The speed of light in vacuum is approximately:

    Show answer & explanation

    Answer: C — 3 × 10⁸ m/s

    c ≈ 2.998 × 10⁸ m/s.

  4. Q4.Find the power dissipated when 1 A flows through a 8 Ω resistor.

    Show answer & explanation

    Answer: D — 8 W

    P = I²R = 1² × 8 = 8 W.

  5. Q5.The unit of electrical resistance is the:

    Show answer & explanation

    Answer: B — Ohm

    Resistance is measured in ohms (Ω).

  6. Q6.Find the kinetic energy of a 5 kg body moving at 6 m/s.

    Show answer & explanation

    Answer: A — 90 J

    KE = ½mv² = ½ × 5 × 6² = 90 J.

  7. Q7.A transformer works on the principle of:

    Show answer & explanation

    Answer: A — Mutual induction

    A changing current in one coil induces a voltage in the other.

  8. Q8.Find the kinetic energy of a 34 kg body moving at 5 m/s.

    Show answer & explanation

    Answer: B — 425 J

    KE = ½mv² = ½ × 34 × 5² = 425 J.

  9. Q9.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.

  10. Q10.What force is needed to accelerate a 14 kg mass at 10 m/s²?

    Show answer & explanation

    Answer: A — 140 N

    F = ma = 14 × 10 = 140 N.

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.
