A short electric dipole has a dipole moment of 16×109 C m. The electric potential due to the dipole at a point at a distance of 0.6 m from the centre of the dipole, situated on a line making an angle of 60° with the dipole axis is:
14πε0=9×109 N m2 C-2
  1. 200 V
  2. 400 V
  3. zero
  4. 50 V

Solution

We know that,

Electric dipole potential, V=14πεpcosθr2, for large distance of r.

V=kPcosθr2=9×109×16×109(0.6)2×12

V=200 V
