COULOMB'S LAW

COULOMB’S LAW The magnitude and direction of the force between two stationary particles, each carrying electric charge, is given by coulomb’s law I) Like charges repel, unlike charges attract ii) The force acts along the line joining the two particles iii)The force is proportional to the magnitude of each charge iv) The force is inversely proportional to the square of the distance b/w the particles F21 α (q2q1/r321)r21 r21/r21 represents the unit vector along the direction r21
