A few electric field lines for a system ...

A few electric field lines for a system of two charges `Q_1` and `Q_2` fixed at two different points on the x-axis are shown in the figure. These lines suggest that

A

`|Q_1|gt|Q_2|`

B

`|Q_1|lt|Q_2|`

C

at a finite distance to the left to `Q_1`, the elctric field is zero

D

at a finite distance to the right of `Q_2`, the electric field is zero.

Text Solution

Verified by Experts
