Answer:
The required potential difference is
.
Explanation:
We know, electric field is nothing but the negative gradiant of potential. Mathematically, in three-dimension,
In one dimension, the magnitude of the electric field is
where ‘
‘ is the applied voltage and ‘
‘is the distance through which the voltage is applied.
Given,
.
So the required potential difference is
