Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
, along the bisector of the angle at –2Q, towards the triangle
Sol. (i) Given diagram is:

(ii) It can be shown in the form of dipoles as

where,
= dipole moment of single dipole
So, net dipole moment is : 
or P net = 
and direction is along the bisector of the angle at –2Q, towards the triangle
