Question

A non-uniform sphere can be kept on a rough inclined plane so that it is in equilibrium. In the figure
below, dots represents location of center of mass. In which one of the positions can sphere be in
equilibrium.
(4) D
(3) C
(2) B
(1) A​

Answer 1

(3) C is correct answer

Explanation:

Given  statement : A non-uniform sphere with four dots A, B, C and D representing location of center of mass residing on  rough inclined plane.

If sphere is in equilibrium state then net torque applied at the point of of contact will be zero.

For that respective line of action, mg needs to be passed through point of contact.

Thus, At C position, sphere is in equilibrium state.
