Question

A sphere is mass m radius R is placed between two vertical walls having separation d which is slightly greater than 2R:

i) Calculate the force exerted by walls in the sphere.
ii) calculate force exerted by ground surface on the sphere.​

Answer 1

Hi mate.......!!!!!!!!!

We know that

F=ma

Mass of the object =M

Acceleration is zero because force is on both direction

So at first case it is zero

At second case it is equal to its mass
