Question

Suppose that, instead of the Coulomb force law, one finds experimentally that the force between any two charge q1 and q2 is Write the appropriate electric field E surrounding a point charge q

Answer 1

Answer: E= KQ/r^2

Explanation: An electric field is a region where an electric charge(positive or negative ) will experience a force.

The magnitude of an electric field E, at a point is given by Coulombs law as

E/ F/q

Where F= Coulombs force exertedon the charge and q= electric charge

E= F/q=(KQq)/r^2q

E=KQ/r^2
