Calculate the velocity of the bob of a simple pendulum at its mean position if it is able to rise to a vertical height of 10 cm. Take `g=9.8 ms^(-2)`.

A

0.6 m/s

B

1.4 m/s

C

1.8 m/s

D

2.2 m/s

Text Solution

Verified by Experts

The correct Answer is:
B

mgh `=1/2 mv^2 implies v= sqrt(2gh)`
`= sqrt(2xx9.8 xx0.1) = 1.4 m//s`
