A particle of mass m is being circulated on a vertical circle of radius r. If the speed of particle at the highest point be v, then

Options

A. `mg=(mv^(2))/(r)`
B. `mg gt(mv^(2))/(r)`
C. `mgle(mv^(2))/(r)`
D. `mg ge(mv^(2))/(r)`

Answer

D

Explanation

If the speed of the particle at highest point be v, then `mg ge (mv^(2))/(r)`
