Answer:
Correct Answer: 23. (a)
Solution:
- (a) Three point charges
and are placed at points , and The system consists of two dipole moment vectors due to and and again due to and ) charges having equal magnitudes qa units - one along and other along . Hence, net dipole moment, along at an angle with positive -axis.
