Read the following passage and answer below Direction of force acting on a charge moving in a magnetic field Since the direction of current is the same as that of the motion of a positive charge, the direction of force acting on it, when moving perpendicular to direction field is the same as that acting on a current carrying conductor placed perpendicular to the direction of magnetic field. The direction of this force is given by Flemming's left-hand rule. Obviously the force acting on a negative charge moving in a direction perpendicular to the field opposite to that acting on a positive charge. Question: When both the magnetic field and the electric field are kept in the same direction, as electron which is moving in this field will
