Answer :

The speed of the particle with respect to sphere is Given

The radius of the smooth sphere is R, the constant acceleration is .

Formula Used

The formula for the total energy in terms of kinetic and potential energy is given as where

The is the total energy in terms of kinetic and potential energy, m is the mass of the object, g is the acceleration in terms of gravity and l is the length of the object, is the angle of exit.

Explanation

As the sphere is moving at a constant acceleration with a pseudo force acting “ ” on the particle opposite to the downward force is .

Therefore, the speed of the particle is The tangential force =  Placing the acceleration as   Integrating both sides we get To know C, we apply boundary pressure of and for which we get:  Hence, the expression of velocity is  Rate this question :
