A bob of mass m is tied with a thread and is made to move in a circular path on a frictionless table surface about point 'O' as shown in diagram. A hypothetical electric field in radial direction exists along the table surface. In this condtion the bob is uncharged and tension is thread is T. If bob is given some charge-

A small disc can slide in a circular path on a frictionless inclined plane inclined at an angle of 30^(@) with the help of a thread as shown. Mass of the disc is m and acceleration due to gravity is g . If the disc is released, when the thread is horizontal, expression for the tension in the thread at the lowest point is
