Question

If the magnitude of intensity of electric field at a distance `x` on axial line and at a distance `y` on equatorial line on a given dipole are equal, then `x:y` is
A. `1:1`
B. `1:sqrt(2)`
C. `1:2`
D. `.^(3)sqrt(2):1`

Answer 1

Correct Answer - d
`E_(ax ial)=E_(equat o rial)implies k.(2p)/(x^(3))=(k.p)/(y^(3))implies (x)/(y)= (2^(1//3))/(1)=^(3sqrt2:1)`
