The correct answer is:
CHECK THE SOLUTION.

Let the sphere move towards left with an acceleration 'a

Let m = mass of the particle
The particle 'm' will also experience the inertia due to acceleration 'a' as it is on the sphere. It will also experience the tangential inertia force ( )) and centrifugal force ( ).

Because,

Integrating both sides we get,

Given that, at , So,
