Vedclass · Answer

(C) According to Fleming's Left-Hand Rule,the direction of the force on a moving charge in a magnetic field is determined by the orientation of the magnetic field,the direction of the current (or motion of positive charge),and the force.For the proton (positive charge moving upwards),the magnetic field is to the right. Using the left-hand rule,the force points into the plane of the paper.For the electron (negative charge moving downwards),the direction of the conventional current is upwards. Since the magnetic field is to the right,the force on the electron points out of the plane of the paper.Therefore,the proton experiences a force into the plane,and the electron experiences a force out of the plane.

$A$ uniform magnetic field exists in the plane of paper pointing from left to right as shown in Figure. In the field,an electron and a proton move as shown. The electron and the proton experience:
