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

`14ms^(-1)`

B

`2ms^(-1)`

C

`3.92ms^(-1)`

D

`5ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Tension of string T =`(mv^2)/®`
`rArr" "25=(0.25xxv^2)/(1.96)`
`rArr" "v=14ms^(-1)`
