The time period of a simple pendulum on the surface of the earth is T. The height above the surface of the earth at which the time period of the pendulum becomes 2 ~T is (Radius of the earth =6400 ~km )
Options
- A3200 ~km
- B6400 ~km
- C1600 ~km
- D800 ~km
Correct answer
A. 3200 ~km
Step-by-step solution
Time period of a simple pendulum is given by, T =2 L g 2 ~T = T 1+ h R 1+ h R = 1 2 aligned & h R =- 1 2 h =- R 2 = 6400 2 & ~h =3200 ~km aligned
