Three identical charges are fixed at the corners of an equilateral triangle . If the force between any two charges is `F`, then the net electric force on each will be

A

`sqrt2F`

B

`Fsqrt3`

C

`2F`

D

`3F`

Text Solution

Verified by Experts

The correct Answer is:
B

Angle between two forces due to individual charges is equal to `60^(@)`
`therefore" "R=sqrt(F^(2)+F^(2)+2F F cos 60^(@))=Fsqrt3`
