On loading a spring with bob, its period of oscillation in a vertical plane is T. If this spring pendulum is tied with one end to the a friction less table and made to oscillate in a horizontal, plane, its period of oscillation will be :

The period of revolution of a satellite in an orbit of radius 2R is T. What will be its period of revolution in an orbit of radius 8R ?

A spherical cavity of radius r is made in a conducting sphere of radius 2 r.A charge q is kept at the centre of cavity as shown in the figure.Find the magnitude of the total electric field at (4r 0) .

A disc of mass 'm' is suspended at a point R/2 above its centre. Find its period of oscillation.

A uniform semicurcular ring having mass m and radius r is hanging at one of its ends freely as shown if Fig. The ring is slightly disturbed so the it oscillates in its own plane. The time period of oscillation of the ring is
