Is Coulomb law is not applicable for that charged particle which is in motion??
hello,
coulomb law is not applicable for moving charges. This is because the information about the position of the charge (the field caused by the charge) can only travel at the speed of light, its applicable even when both charges are at rest. Charge does not necessary has to move for Coulomb's law to be applicable.
Hello candidate,
Coulomb law cannot be applicable for a charged particle in motion, it is because the formula of coulomb law contains the value of the distance in its formula. So if the particle is in motion, how will you able to determine the distance as it would keep on changing since the body is in motion. The formula goes as : F= kq1q2/(r^2). Hope it helps you to understand.
Thankyou!
