If the length of second pendulum becomes four times, then its time period will become:
Correct answer: B. Two times
- A. Four times
- B. Two times
- C. Half
- D. one fourth
Explanation
By understanding the relationship between the length of a pendulum and its time period, we can deduce that if the length becomes four times, the time period will become two times. This is because the time period is proportional to the square root of the length.

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.
