Answer:
The coordinates of the point is (0,0.55).
Explanation:
Given that,
First charge
at origin
Second charge
Second charge at point P = (0,1)
We assume that,
The net electric field between the charges is zero at mid point.
Using formula of electric field







Hence, The coordinates of the point is (0,0.55).
In order to design an experiment, you need a hypothesis about the scientific question you are trying to answer.
The distance the spring stretches is the answer.
I hope this helps.
