Two small identical electric dipoles AB and CD, each of dipole moment 'p'are kept at an angle of 120° to each other in an external electric field 'E' pointing along the x-axis as shown in the figure. Find the
(a) dipole moment of the arrangement, and
(b) magnitude and direction of the net torque acting on it.
OR
In the figure given below, find the
(a) equivalent capacitance of the network between points A and B. Given : C1=C5=8µF, C2=C3=C4=4µF.
(b) maximum charge supplied by the battery, and
(c) total energy stored in the network.
