Question

Consider the coordinate system in the diagram bellow; the z axis points out of the page. At the point (-d, 0, 0) a ball of mass m is initially  (at t= 0) at rest, but it is dropped under the face of gravity, near the Earth.  We ignore air resistance as usual, and treat ball as a point mass. 

Find the net torque of this particle at time t>0.
