Two spheres A and B of the same mass m and the same radius are placed on a rough horizontal surface. A is a uniform hollow sphere and B is uniform solid sphere. They are tied centrally to a light spring of spring constant k as shown in figure. A and B are released when the extension in the spring is `x_(0)`. Friction is sufficient and the spheres do not slip on the surface. Find the frequency and amplitude of SHM of the sphere A.

Answer

`f=(1)/(2pi) sqrt((46k)/(35 g)) ; A_(1)=(21)/(46) x_(0)`
