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?

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 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?

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?

The angular momentum of the atom about the centre of mass will be

Angular Momentum of a Body Rotating About Fixed Axis of Rotation

If the angular momentum of a rotating body about an axis is increased by 10%. Its kinetic energy increases by

The angular momentum of an electron is zero. In which orbital may it be present?

A : If angular momentum of an object is constant about a point then net torque on it about that point is zero. R : Torque is equal to the rate of change of angular momentum.

a) show that the energy of a rolling body which is not slipping is equivalent to that of pure rotatioin with the same angular speed about an axis through the point of contact of the rolling body. b) Show that the angular momentum of a body of mass M which is rolling without slippint about any point is equal to its angular momentum about its center plus the moment of momentum of a particle of the same mass M concentrated at its center and moving with the speed of the center of the mass of the body about the same point
