Find the contact forces acting on a stationary sphere weighing 10 N is placed in a fixed frame BAC as shown in the diagram? (Assume `theta` is constant)

Text Solution

Verified by Experts

Normal force exerted by AC on sphere is 10N and by AB is zero as `theta` is constant. (Note, thogh AB is in contact with the sphere, it is not exerting any normal reaction on sphere.)
