If the time period of a two meter long simple pendulum is 2 s , the acceleration due to gravity at the place where pendulum is executing S.H.M. is:

Options

  1. A2 π 2   m   s - 2
  2. B16   m   s - 2
  3. Cπ 2   m   s - 2
  4. D9 . 8     m   s - 2

Correct answer

A. 2 π 2   m   s - 2

Step-by-step solution

T = 2 π l   g 2 = 2 π 2 g ⇒ g = 2 π 2
