Charge `2q and -q` are placed at `(a,0) and (-a, 0)` as shown in the figure. The coordinates of the point at which electric field intensity is zero will be `(x,0)` where

A

`-altxlta`

B

`xlt-a`

C

`xgt-a`

D

`0ltxlta`

Text Solution

Verified by Experts

The correct Answer is:
B
Between `2q` and `-q`, two electric fields are in same direction. So their resultant can't be zero. To the right of `2q` left of -q they are in opposite directions. So net field will be zero nearer to charge having small magnitude.
