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

14 m/s

B

3 m/s

C

3.92 m/s

D

5 m/s

Text Solution

Verified by Experts

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