A ball of mass `m` is rotating in a circle of radius `r` with speed `v` inside a smooth cone as shown in figure. Let `N` be the normal reaction on the ball by the cone, then choose the correct option:

A

`N costheta=mg`

B

`g sintheta=v^(2)/r costheta`

C

`N sintheta-(mv^(2))/r=0`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`N=mg cos theta(mv^(2))/r=mg sin theta`
