Six charges +q each are placed at the corners of a regular hexagon of each side a. The electric field at the centre of the hexagon is

A

a) zero

B

`b) (1)/(4pi epsi_(0)).(q)/(a^(2))`

C

`c) (1)/(4pi epsi_(0)).(6q)/(a^(2))`

D

`d)(1)/(4pi epsi_(0)).(3q)/(a^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
The electric field at the centre of the hexagon is zero. Since, due to symmetry in hexagon geometry vector sum of all electric fields by each charge particle cancel out each other.
