Consider a block moving in a horizontal circular path on the inner surface of a cone. The normal force on the block is :

A

mg

B

always greater then mg

C

may be greater or less than mg

D

always less than mg

Text Solution

Verified by Experts

The correct Answer is:
B

(B) `(v^(2))/(r)=g cot theta`
`N=m[g sin theta + (v^(2))/(r)cos theta]`
`N= (mg)/(sin theta) gt mg`.
