The time period of a simple pendulum of ...

The time period of a simple pendulum of infinite length is (R=radius of earth).

A

infinite

B

24 hours

C

96.4 minutes

D

84.6 minutes

Text Solution

Verified by Experts

The correct Answer is:
D
`T = 2pi sqrt((1)/((1)/(g)((1)/(l) + (1)/(R))))`
`l = oo`
`T = 2pi sqrt((R)/(g)) = 84.6 ` min
