Mass of the bob of a simple pendulum of ...

Mass of the bob of a simple pendulum of length `L` is `m`. If the bob is projected horizontally from its mean position with velocity `sqrt(4 gL)`, then the tension in the string becomes zero after a vertical displacement of

A

`L/3`

B

`3L/4`

C

`4L/3`

D

`5L/3`

Text Solution

Verified by Experts

The correct Answer is:
`(4)`
`v = sqrt(g(3h - r))` Where h is maximum height at which the tension in the string is zero.
