Five point charge each having magnitudes...

Five point charge each having magnitudes `q` are placed at the corner of hexagon as shown in figure. Net electric field at the centre `'O'` is `vec(E )`. To get net electric field at `'O'` be `6 vec(E )`, charge placed on the remaining sixth corner should be

A

`6q`

B

`-6q`

C

`5q`

D

`-5q`

Text Solution

Verified by Experts

The correct Answer is:
D
To obtained net field `6E` at centre `O`, the charge to be placed at remaining sixth corner is `-5q`. (see following figure)
