The electric potential (V) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation:
Here,
k = Coulomb's constant
Q = Charge
r = Distance
If we rearrange the equation to find the distance we have,
Now the value of the charge density is equivalent to the charge on the surface area of the sphere this is
