Two charges A and B enter a magnetic field such that the direction of both charges is perpendicular to that field. Both charges experience magnetic (centripetal) force and adopt a curved path. 1. Suppose that the charge A has more mass than charge B and everything else is same for both charges. What will be the difference between the paths of both charges? 2- Suppose that the charge A is moving with a higher velocity than charge B and everything...
