MCQ Answer Key
| Q.No. | Answer | Explanation |
|---|---|---|
| 1 | C | Period T = 2π/ω for x = A cos(ωt). |
| 2 | B | Velocity v = fλ = 500 × 0.7 = 350 m/s. |
| 3 | A | Max acceleration a = ω²A = (k/m)A = kA/m. |
| 4 | A | SHM requires acceleration ∝ displacement and opposite in direction. |
| 5 | A | T = 2π√(l/g) for a simple pendulum. |
| 6 | A | ω = √(g/L) for pendulum motion. |
| 7 | B | Resonance when driving frequency = natural frequency of system. |
| 8 | A | Frequency = coefficient of t/2π; 4π/2π = 2 Hz. |
| 9 | B | Velocity is maximum at mean position, v = ωA. |
| 10 | C | F = kx = 200 × 0.02 = 4 N; but 2 cm = 0.02 m, so 200 × 0.02 = 4 N. |

| 12 | B | Beats occur when two waves have close frequencies. |
| 13 | C | SHM is not constrained to circular paths. |

| 17 | C | Potential energy and kinetic energy equal maximum values, but max velocity ≠ max amplitude. |
| 18 | B | ω² = 4, so ω = 2 rad/s. |
| 19 | A | v = fλ = 500 × 0.5 = 250 m/s. |
| 20 | B | g ≈ 0 makes T = ∞ for a pendulum on satellite. |
