For small amplitudes, the force constant of a simple pendulum is

A

directly proportional to the acceleration due to gravity

B

inversely proportional to the acceleration due to gravity

C

independent of the mass of the bob and the length of the pendulum

D

directly proportional to the mass of the bob

Text Solution

Verified by Experts

The correct Answer is:
D
Restoring Force `=mg "sin" theta = mg (x)/(l)`
and `K=(F)/(x)=(mg)/(l) therefore F prop m`
