In a stationary lift, time period of a simple pendulum is ' T '.' The lift starts accelerating downwards with acceleration ( g 4 ) , then the time period of the pendulum will be

Options

  1. A3 2 ~T
  2. B2 3 ~T
  3. C3 4 ~T
  4. D4 3 ~T

Correct answer

B. 2 3 ~T

Step-by-step solution

Time period of pendulum: T=2 L g When lift is accelerated downward with acceleration g 4 , aligned & g=g- g 4 & g= 3 g 4 aligned New Time period will be aligned & T ₁=2 4 ~L 3 ~g & ~T ₁=2 2 3 L g & T ₁= 2 3 ~T aligned
