A point charged q placed at (3a, 0) and ...

A point charged q placed at `(3a, 0)` and another charge `-2q` is placed `(-3a, 0)`
If we plot a graph of potential `(V)` on x-axis it will like

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
At `x=-3a` & `x=3a`, the potential becomes `-oo` & `+oo` respectively and from the above question potential becomes zero at (a, 0) and (9a, 0)
