Electric field at a far away distance r ...

Electric field at a far away distance r on the axis of dipole is `vecE_(0)`. What is the electic field at a distance 24 on perpendicular bisector?

A

`(vecE_(0))/16`

B

`-(vecE_(0))/16`

C

`(vecE_(0))/8`

D

`-(vecE_(0))/8`

Text Solution

Verified by Experts

The correct Answer is:
B
`vecE_(0)=(2kp)/(r^(3))(hatp)`……….1
`vecE=(kp)/((2r)^(3))(-hatp)`
`vecE=-18((kp)/(r^(3)))hatpimpliesvecE=-(vecE_(0))/16` from 1
