Homework Statement
Radial component of an electric field near charge 'q'.
E = (1 / 4∏ε) * (q/r^2)
Need to find the potential of this which is done through integrating this and taking the negative answer, i.e.
ΔV = -∫E dr
This is to be along a radial path towards the charge, starting from infinity to r2.
The Attempt at a Solution
So I have
ΔV = - (q/4∏ε) ∫1/r^2 dr
As the charge is constant.
Just unsure on the limits, I'm guessing its ∞ and r2, would that be right?
