What is the period of a pendulum formed by pivoting a metre stick so that is free to rotate about a horizontal axis passing through the `75 cm` mark?

What is torque due to gravity about an axis passing through C.M.?

A metallic rod of mass m length R is pivoted at O. It is free to rotate about a horizontal axis passing through O . An inward magnetic field is applied as shown in the figure. Find the ratio of maximum electric field inside the metallic rod to the applied magnetic field induction .

A massless stick of length L is hinged at one end and a mass m attached to its other end. The stick is free to rotate in vertical plane about a fixed horizontal axis passing through frictionless hinge. The stick is held in a horizontal position. At what distance x from the hinge should a second mass M = m be attached to the stick, so that stick falls as fast as possible when released from rest

A solid cube of side l is made to oscillate about a horizontal axis passing through one of its edges. Its time period will be

Torques of equal magnitude are applied to a hollow cylinder and a solid sphere, both having the same mass and radius. The cylinder is free to rotate about its standard axis of symmetry, and the sphere is free to rotate about an axis passing through its centre. Which of the two will acquire a greater angular speed after a given time.
