Three point charges are kept at the three corners of an equilateral triangle of edge length a, as shown in the figure. The net electric dipole moment of the system is

A

0

B

`qasqrt3`

C

`qasqrt2`

D

qa

Text Solution

Verified by Experts

The correct Answer is:
B
The given system is equivalent to two electric dipoles of dipole moment qa inclined at an angle `60^@` to each other. Hence, the resultant dipole moment will be `qasqrt3`.
