Question

The Electric Field at a point charge is 26N/C and the Electric Potential at that point is 13J/C.
Calculate the distance of the point from the charge and magnitude of charge.

Answer 1

The distance from the point of charge can be calculated through the formula of electric field and electric potential.

Electric field,

Potential difference,

On dividing both the formula, we get,

So, the distance from the point from the charge is  0.5 m

Now, magnitude of charge,

So, the magnitude of the charge is 0.56 nC
