Question

The electric field at a point on the axial line at a distance
of 10 cm from the centre of an electric dipole is 3.75 x 10^5 N
C-1 in air, while at a distance of 20 cm, the electric field is
3 x 10^4 NC-1. Calculate the length of the electric dipole.​

Answer 1

Answer:

The electric field at a point on the axial line at a distance of 10 cm from the centre of an electric dipole is 3.75x${{10}^{5}}$ N/C in air, while at a distance of 20 cm, the electric field is 3 x ${{10}^{4}}$ N/C.
