The period of simple pendulum double when :

Correct answer: C. Its length is made four time

  • A. Its length is doubled
  • B. The mass of the bob is double
  • C. Its length is made four time
  • D. The mass and length of the pendulum is made two times

Explanation

The correct option is C Its length is made four times T = 2π√l/g⇒T∝√l , When length will be four times then,T =√4 =2 According to this relation,

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.
