Choose the correct answer. When a point of suspension of pendulum is moved vertically upward with acceleration ' a ', its period of oscillation

Options

  1. Adecreases
  2. Bincreases
  3. Cremains same
  4. Dsome times increases and some times decreases

Correct answer

A. decreases

Step-by-step solution

For a simple pendulum, T =2 l ~g ~T 1 ~g When the point of suspension is moved vertically upwards with acceleration a, g becomes g+a . Hence, T decreases.
