A small elecric diple is placed at orgigen with its axis being directed along the ppositive x-axis . The direction of electric field due to the diple at a point ` ( 1 m, sqrt 2 m, 0) ` is along rhwra-

A

Z-axis

B

y-axis

C

x-axis

D

line `y=x`

Text Solution

Verified by Experts

The correct Answer is:
B
`|vec E_1| =` field due to Pcos ` theta` at `P= (2K cos theta)/r^2`
`|vec E_2| =` field due to `P sin theta` at `P= (KP sin theta)/r^2`
`|vec E_P = vec E_1 + vec E_2 rArr E_(p(x)) =E_(2(x)) =0`
so ` vec E_P` is along `y` axis .
