A ball of mass 0.25 kg attached to the end of a string of length 1.96 m is moving in a horizontal circle. The string will break if the tension is more than 25 N . What is the maximum speed with which the ball can be moved

A

`14m//s`

B

`3m//s`

C

`3.92m//s`

D

`5m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`T=(mv^(2))/(r)therefore 25=(0.25xxv^(2))/(1.96)therefore v=14m//s`.
