# A RIGID PROBLEM ON A RUBBER RING

**Classical Mechanics**Level 3

A smooth right circular cone of semi vertical angle 'A' is at rest on a horizontal plane. A rubber ring of mass 2.5 kg which requires a force of 15 N for an extension of 10 cm is placed on the cone.Find(in cm),the increase in radius of ring in equilibrium. GIVEN:-tan A=(5/12)
