Electric Field of a Dipole
An electric dipole consists of charges +q and -q separated by a distance d. At a point on the perpendicular bisector of the dipole, a distance r from its center where r >> d, how does the magnitude of the electric field, E, depend on the distance r?
A
E ∝ 1/r
B
E ∝ 1/r⁴
C
E ∝ 1/r²
D
E ∝ 1/r³
