## Main Question or Discussion Point

We all know the coulomb's law of electrical force between two charges [itex]q_1[/itex][itex],q_2[/itex] equals to [itex]\normalsize F= Kq_1q_2/d^2[/itex]. But this law is not precisely true when the two charges are moving. We know for a single charge q moving with a velocity v the force is [itex]\ F=q(E+v×B)[/itex]

What is the straightforward formula of electrical force
