A point `A` on a sphere of weight `w` rests in contact with a smooth vertical wall and is supported by a string joining a point `B` on the sphere to a point `C` on the wall. Draw free body diagrame of the spheres.

Two sphere A and B are placed between two vertical walls as shown in figure. Draw the free body diagrams of both the spheres

A small body b starts from rest at the hightest point A of a large fixed sphere , with centre C ,and slides down with a small but constant speed , then ,the coefficent of friction between B and the sphere ,at any point P on the surface of the sphere such that angle ACP=theta, must be equal to

A rod AB of weight w_(1) is placed over a sphere of weight w_(2) shown in figure.Ground is rought and there is no friction between rod and sphere and sphere and wall. Draw free body diagrame of sphere and rod separalety.

Two spheres A and B are placed between two vartical walls as shown in figure .Friction is absent everywhere. Draw the free body diagrame of both the spheres.

Two spheres A and B are placed between two vartical walls as shown in figure .Friction is absent everywhere. Draw the free body diagrame of both the spheres.

A rod AB of weight w_(1) is placed over a sphere of weight w_(2) shown in figure.Ground is rough and there is no friction between rod and sphere and sphere and wall. Draw free body diagram of sphere and rod separately.

A sphere rolling on a horizontal rough surface collides elastically with a smooth vertical wall, as shown in figure. During collision, angular momentum of the sphere is conserved about ____________. (Any point O on the surface/point of contact P)
