The length of a second’s pendulum at the surface of earth is 1 m. The length of second’s pendulum at the surface of moon where g is 1/6th that at earth’s surface is

A

1/6 m

B

6 m

C

1/36 m

D

36 m

Text Solution

Verified by Experts

The correct Answer is:
A
`T=2pi sqrt((l)/(g)),2=2pi sqrt((l)/(g))=2pi sqrt((l.)/((g//6)))`
Time period will remain constant if on moon,
`l.=l//6=1//6` m
