Question

A ball of mass `0.25kg` attached to the end of a string of length `1.96m` moving in a horizontal circle. The string will break if the tension is more than `25N`. 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`

Answer 1

Correct Answer - A
`T=(mv^(2))/(L)le25`
`((0.25)(v^(2)))/(1.96)le25`
`vle14`
`v_(max)=14m//s`
