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

2.2 m/s

B

1/8 m/s

C

1.4 m/s

D

0.6 m/s

Text Solution

Verified by Experts

The correct Answer is:
C
Law of conservation of energy-
`(1)/(2)mv^(2)=mgh`
`implies v=sqrt(2gh)=sqrt(2xx9.8xx0.1)`
`implies v=1.4m//s`
