Electric field at a far away distance r on the axis of a dipole is 
. What is the electric field at a distance 2r on perpendicular bisector?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
As we know electric field 
along the axis of dipole
… (i)
where p is dipole
The electric field in the direction of perpendicular bisector of dipole at distance 2r
… (ii)
From Eqs. (i) and (ii), we get
Hence, E is in the opposite direction of p
Hence,
