A dipole is placed at origin of coordinate system as shown in figure, find the electric field at point ` P (0, y)`
.

Text Solution

Verified by Experts

The correct Answer is:
`(KP)/(sqrt(2)y^(3))(-hat(i)-2hat(j))`

`vec(E)_(x)=(-K(P cos 45^(@)))/y^(3) hat(i)`
`vec(E)_(y)=(-2x(P sin 45^(@)))/y^(3) hat(j)`
`vec(E)_(P)=(KP)/(sqrt(2)y^(3))[-hat(i)-2hat(j)]`
