A ring of radius 'r' and mass per unit length 'm' rotates with an angular velocity `'omega'` in free space then :

A ring of mass m and radius R is being rotated about its axis with angular velocity omega . If a increases then tension in ring

A ring of mass m and radius R is being rotated about its axis with constant angular velocity omega in the gravity free space. Find tension in the ring.

A nonconducting ring of radius R has charge Q distributed unevenly over it. If it rotates with an angular velocity omega , the equivalent current will be

A conducting ring of radius R has charge Q distributed unevenly over it. If it rotates with an angular velocity omega , the equivalent current will be

A ring of radius R is first rotated with an angular velocity omega and then carefully placed on a rough horizontal surface. The coefficient of friction between the surface and the ring is mu . Time after which its angular speed is reduced to half is
