It torque is zero, then

If the net torque acting on the body is zero, then the body is in

When torque acting on a rotating body is zero, then which of the following remains constant?

A rectangular coil of sides 8cm and 6cm haivng 2000 turns and carrying a current of 200mA is placed in a uniform magnetic field of 0*2T directed along the positive x-axis. (a) What is the maximum torque the coil can experience? In which orientation does it experience the maximum Torque? (b) For which orientations of the coil is the torque zero? When is this equilibrium stable and unstable?

If net external torque, about a point, acting on the system is zero, then we can surely say:

The position vector of a particle with respect to origin "0" is vec r .If the torque acting on the particle is zero,then
