A short electric dipole has dipole moment of ` 1 xx 10^(-9) C ` m . Determine the electric potential due to the dipole at a point distance 0.3 m from the centre of the dipole situated
on the axial line

Text Solution

Verified by Experts

Given
`P = 1 xx 10 ^(-9) ` Cm
`r = 0 . 3 ` m
Potential at a point on the axial line
`V = (1)/(4 pi epsilon _(0)) (p)/(r^(2)) = (9 xx 10 ^(9) xx 1 xx 10 ^(-9))/((0.3)^(2)) = 100` volt
