Torque - 2

Class 11 NEET 2020 - Revision In 60 Days | Rigid Body Dynamics Part -2 (Torque) - Quick Revision | NEET Physics | Important Questions

If a body starts rotating from rest because of a torque of 2 Nm, then its kinetic energy after 20 revolutions will be

A torque of 2.5 Nm acts on a current carrying rectangular coil of area 0.2 m^(2) , suspended vertically in a uniform magnetic field. What is the torque, if the rectangular coil is replaced by a plane circular coil of the same area? [all other quantities are unaltered]

Statement -1: It is harder to open and shut the door if we apply force near the hinge Statement -2: Torque is maximum at hinge of the door.

The drwing shows a bicycle wheel of radius r, resting against a small step whose height is h = r//5 . A clockwise torque increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. Let this torque be T. What is the magniitude of the horizontal component of the acceleration of the centre of the wheel when a torque of 2T is applied? Assume that the wheel doesn't slip at the edge of the step when this torque is applied (ignore the mass of the spokes).

Torque is a __________ quantity.
