dipole torque problem.. Help please!
Hi, the problem is:
Show that if the force action on a dipole p placed in an Non uniform electric field is p\cdot \nabla E_{ext}, the torque acting on the dipole in this field is
\tau =r \times (p\cdot\nabla E_{ext})+p\times E_{ext}
where r is the vector distance to the dipole from the point about which the torque is to be measured.
How can i do this? it's urgent.. please!
