In question number 45, what will be the electric field at centre O, if the charge from one of the corners (say A) is removed?

A

`q/(4piepsilon_(0)r^(2))` along OA

B

`(2q)/(4piepsilon_(0)r^(2))` along OB

C

`(q^(2))/(4piepsilon_(0)r^(2))` along OC

D

`(2q)/(4piepsilon_(0)r^(2))` along OA

Text Solution

Verified by Experts

The correct Answer is:
A
When a charge q from corner A is removed, electric field at O is `E_(1)=q/(4piepsilon_(0)r^(2)` along OA
