12th Physics Book in Tamil Objective for Students

A ball starts from rest and rolls down a 30° inclined plane. How much time would it take to cover 14 meters?

The area under the torque vs. time curve gives:

The ratio of the torque to the angular momentum of a processing body gives:

The moment of inertia (M.I.) of a uniform cylinder about an axis is equal to its M.I. about the axis of rotation passing through its center of gravity and perpendicular to the axis of the cylinder. If the length of the cylinder is 20 cm, its radius in centimeters will be:

A disc of radius 2 meters and mass 200 kg is acted upon by a torque of 100 N-m. The angular acceleration in radian/second² would be:
