The magnitudes of electric field and of the electric potential on the axis of an electric dipole at a distance 'r' from its centre are E and V, respectively. The magnitude of the electric field and potential at the same distance 'r' on its equatorial line will be: (given r >> a, where 2a is dipole length)
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $\frac{E}{2}, 0$
The electric field on the equitorial line is -
$E_{axial}=2E_{equitorial}$
The electric potential on the equitorial line is zero.
