A body is in translational equilibrium under the sctin of coplanar forces. If the torque of these force is zero about a point is it necessary that it will also be zero abut any other point?

If the resultant torque of all the forces acting on a body is zero about a point is it necessary that it will be zero about any other point?

If the angular momentum of a body is zero about some point. Is it necessary that it will be zero. About a differet point?

If the angular momentum of a body is found to be zero about a point is it necessary that it will also be zero about a different point?

For a body to be in equilibrium under the combined action of several forces

If a body is in equilibrium under a set of non-collinear forces, then the minimum number of forces has to be

A body is in equilibrium under the action of three coplanar forces P,Q and R as shown in figure. Select the correct statement.

If the net force acting on a body be zero , will it remain necessarily at rest ?

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.

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 ?
