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 a line making an angle of `60^(@)` with the dipole axis

Text Solution

Verified by Experts

Given
`P = 1 xx 10 ^(-9) ` Cm
`r = 0 . 3 ` m
Potential at a point on a line making an angle of ` 60^(@)` with the dipole axis is
` V = (1)/(4 pi epsilon_(0)) (p cos theta)/( r^(2)) = (9 xx 10 ^(9) xx 1 xx 10 ^(-9) cos 60^(@))/((0.3)^(2))`
