Three charges +q, +q, +2q are arranged as shown in figure. What is the field at point P (center of side AC)

A

`E=q/(pi epsilon_(0)a^(2))`

B

`E=q/(2 pi epsilon_(0)a^(2))`

C

`E=q/(3 pi epsilon_(0)a^(2))`

D

`E=q/(4 pi epsilon_(0)a^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=1/(4 p epsilon_(0)) (2q)/((BP)^(2))`
`BP=sqrt(BC^(2)-PC^(2))a//sqrt(2)`
