If the mass attached with a spring becomes four times, the time period of vibration becomes:
Correct answer: D. Double
- A. One fourth
- B. 3/4
- C. Half
- D. Double
Explanation
Explanation: T = 2π√m/kKeeping in mind the above relation, time period is directly proportional to the square root of mass. So, the correct answer is D.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
