Answer #1

Correct option is D.

Force of attraction between two point charges is given by:

F = k*q1*q2/r^2

Which is known as Coulomb's law

Here, q1, q2 = point charges, r = distance between point charges

Ohm's law: Used to find current in a wire, where I = V/R

V = Potential difference, R = resistance of wire

Ampere's law: gives relation between magnetic field and current through a loop

Faraday's law: Used to find induced emf in a current carrying loop in magnetic field.

Let me know if you've any query.
