Question
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:
Options
A.
B.
C.
D.
Solution
Potential energy = −
; where, 
= Electric field due to dipole P2.
∴ U12 = − (P1) (E2)
U12 = − (P1)
; where, = Electric field due to dipole P2.∴ U12 = − (P1) (E2)
U12 = − (P1)
