An electric dipole is placed along the x-axis at the origin O. A point P is at a distance of 20cm from this origin such that OP makes an angle `(pi)/(3)` with the x-axis. If the electric field at P makes an angle `theta` with the x-axis the value of `theta` would be ................

A

`(pi)/(3)+tan^(-1)((sqrt(3))/(2))`

B

`(pi)/(3)`

C

`(2pi)/(3)`

D

`tan^(-1)((sqrt(3))/(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`theta=(pi)/(3)+alpha, tanalpha=(1)/(2)tan""(pi)/(3)impliesalpha=tan^(-1)((sqrt(3))/(2))`
So `theta=(pi)/(3)+tan^(-1)((sqrt(3))/(2))`
