Two short electric dipoles are placed as shown (r is the distance between their centers). The energy of electric interaction between these dipoles will be:
(C is center of dipole of moment P 2 )
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Potential energy = – 
; where, 
= Electric field due to dipole P 2 .
U 12 = – (P 1 ) (E 2 )
U 12 = – (P 1 )
