Electro statics

Two charges +3μ C and -3 μ C are separated by a very small distance of 5 m.m.
a). What is the name of the above arrangement
b). If the above arrangement is placed in a uniform electric field of intensity 3×10-5 N/C with
its axis perpendicular to the field direction, what is the torque acting on it?
c. If the arrangement is placed in a non uniform electric field, what happens?
