Question

Electric field intensity at axis of dipole of other side of dipole is 20 n/c than electric field intensity at equatorial line

Answer 1

electric field intensity due to dipole at equatorial line is 10 N/C.

It has given that electric field intensity at axis of dipole is 20 N/C.

we have to find the electric field intensity at equatorial line.

let p is dipole moment and r is seperation between midpoint of dipole to point of observation.

then electric field intensity due to dipole at axial line, E_a = 2kp/r³ ......(1)

electric field intensity due to dipole at equatorial line, E_e = kp/r³.......(2)

from equations (1) and (2) we get,

E_a = 2E_e

⇒20 = 2E_e

⇒E_e = 10 N/C

therefore, electric field intensity due to dipole at equatorial line is 10 N/C.
