A particle of mass `m` is moving with constant speed in a vertical circle in `X-Z` plane. There is a small both at some distance on `Z-`axis. The maximum distance of the shadow of the particle on `X-`axis from origin equal to `:-`

Options

A. `(175)/(24)m`
B. `(125)/(24)m`
C. `25m`
D. `24m`

Answer

A

Explanation

`sintheta=(7)/(25),costheta=(24)/(25)`
`xcostheta=7rArrx=(7)/(costheta)=(7xx25)/(24)=(175)/(24)m`
