Question

the electric field on the axis of dipole at a distance of x cm from the center is 3*10^5 N/C calculate the electric field at the distance of x cm on the equator of the dipole

Answer 1

Answer :

The electric field on the axis of dipole at a distance of x cm from the centre is 3×10⁵ N/C.

We have to find magnitude of electric field at the distance of x cm on the equator of the dipole.

$\star$ Electric field is the region around charged particle or charged body in which if another charge is placed, it experiences electrostatic force.

• The direction of the electric field at an axial point of an electric dipole is same as that of its dipole moment and at an equatorial point it is opposite to that of dipole moment.

The strength of electric field at an axial point of a short dipole is twice the strength at the same distance on the equatorial line.

$\bigstar\:\underline{\boxed{\tt{\red{E_{axial}=2E_{equatorial}}}}}$

➝ E(a) = 2E(e)

➝ 3 × 10⁵ = 2E(e)

➝ E(e) = 3/2 × 10⁵

➝ E(e) = 1.5 × 10⁵ N/C
