An electric dipole is placed along x–axis at the origin as shown in the figure. Electric field at the point P is parallel to the y–axis. If x–coordinate of P `sqrt2` is m, what is its y–coordinate?

A

1 m

B

2 m

C

3 m

D

4 m

Text Solution

Verified by Experts

The correct Answer is:
B
`E_"net"` along y-axis `rArr (KP sin^2 alpha)/r^2 = (2KPcos^2alpha)/r^2`

`rArr` y =2m
