1. Suppose that the strength of the electric field about an isolated point charge has a certain value at a distance of 1 m. How will the electric field strength compare at a distance of 2 m from the point charge?
I know it's At twice the distance the field strength will be 1/4 but what law applies here?
(Boyle's law, the universal law of electrical force, Coloumb's law or the inverse-square law)
