    The vector sum of a system of non-collinear forces acting on a rigid body is given to be non-zero. If the vector sum of all torques due to the system of forces about a centain point is found to be zero, does this mean that it is necessarily zero about any arbitrary point ?

    A : For a body to be in rotational equilibrium the net torque acting on the body about any point is zero. R : For net torque to be zero, net force should also be zero.
