Problem

In a certain region of space, electric field is along the

z

-direction throughout. The magnitude of electric field is, however, not constant but increases uniformly along the positive

z

-direction, at the rate of

10^5\,\text{N C}^{-1}\,\text{m}^{-1}

. What are the force and torque experienced by a system having a total dipole moment equal to

10^{-7}\,\text{C m}

in the negative

z

-direction? (a) Force experienced by the system. (b) Torque experienced by the system.
