A ring of radius R is rolling purely on the outer surface of a pipe of radius 4R At some instant the center of the ring has constant speed =v then the acceleration of the point on the ring which is in contact with the surface of the pipe is

A convex surface has a uniform radius of curvature equal to 5R. A wheel of radius R is rolling without sliding on it with a constant speed v . Find the acceleration of the point (P) of the wheel which is in contact with the convex surface.

A thin ring of mass m and radius R is in pure rolling over a horizontal surface. If v_0 is the velocity of the centre of mass of the ring, then the angular momentum of the ring about the point of contact is

A thin ring of mass m and radius R is in pure rolling over a horizontal surface. If v_0 is the velocity of the centre of mass of the ring, then the angular momentum of the ring about the point of contact is

A ring of radius R rolls on a horizontal surface with constant acceleration a of the centre of mass as shown in figure. If omega is the instantaneous angular velocity of the ring. Then the net acceleration of the point of contact of the ring with gound is

A ring of radius R rolls on a horizontal surface with constant acceleration a of the centre of mass as shown in figure. If omega is the instantaneous angular velocity of the ring. Then the net acceleration of the point of contact of the ring with gound is

In case of pure rolling, what will be the velocity of point A of the ring of radius R?

In case of pure rolling, what will be the velocity of point A of the ring of radius R?

A ring of radius R has charge -Q distributed uniformly over it. Calculate the charge that should be placed at the center of the ring such that the electric field becomes zero at apoint on the axis of the ring at distant R from the center of the ring.
