Consider a positively charged infinite cylinder with uniform volume charge density ρ > 0. An electric dipole consisting of +Q and -Q charges attached to opposite ends of a massless rod is oriented as shown in the figure. At the instant as shown in the figure, the dipole will experience,
1
a force to the left and no torque.
2
a force to the right and a clockwise torque.
3
a force to the right and a counter clockwise torque.
4
no force but only a clockwise torque.
