Vedclass · Answer

(A) When two electrons move parallel to each other with the same velocity,they experience two types of forces:$1$. Electrostatic force: Since both are negatively charged,they experience a repulsive force given by Coulomb's law: $F_e = \frac{1}{4\pi\epsilon_0} \frac{e^2}{r^2}$.$2$. Magnetic force: Moving charges constitute a current. Two parallel currents in the same direction attract each other. The magnetic force is given by $F_m = \frac{\mu_0 e^2 v^2}{4\pi r^2}$.Comparing the magnitudes,the electrostatic repulsive force is much stronger than the magnetic attractive force (by a factor of $c^2/v^2$,where $c$ is the speed of light). Therefore,the net force is repulsive.

Two electrons are moving along parallel lines in the same direction with the same velocity. They will:
