Read the following passage and answer below <br><br> Direction of force acting on a charge moving in a magnetic field <br><br> 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 of magnetic 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. <br> <br> Question : The force of an electron moving a magnetic field is

Question

$\begin{array}{1 1} (a)\; \text{opposite to that acting on a positive charge} \\ (b)\; \text{same direction to that acting on a positive charge} \\ (c)\; \text{in the downward direction} \\ (d)\; \text{cannot be determined} \end{array}$
