A) \[2ql\,\hat{j}\]
B) \[(ql)\,\frac{\hat{i}+\,\hat{j}}{\sqrt{2}}\]
C) \[\sqrt{3}ql\,\frac{\,\hat{j}-\hat{i}}{\sqrt{2}}\]
D) \[-\sqrt{3}ql\,\hat{j}\]
Correct Answer: D
Solution :
The given system of charges can be considered to consists of two dipoles of charges\[+q\,\,and\,\,-q\]. Let p be the dipole moment by the dipole of charges \[+q\,\,and\,\,-q\] (placed at point B)You need to login to perform this action.
