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

Options

A. `mg`
B. always greater then mg
C. may be greater or less than mg
D. always less than mg

Answer

B

Explanation

Consider a block…………

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