What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of 10 cm (take `g=9.8m//s^(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`
