Answer

Explanation:

Step1: Apply right - hand rule for positive charges

For a positive charge, the right - hand rule states that if the thumb points in the direction of the velocity of the charge and the fingers point in the direction of the magnetic field, the palm points in the direction of the magnetic force. Here, the velocity of the charge is from south to north and the magnetic field is from east to west. If it were a positive charge, using the right - hand rule, the force would be toward the ceiling.

Step2: Adjust for negative charge

Since the charge is negative, the direction of the force is opposite to that of a positive charge. So the force on the negative charge is toward the floor.

Answer:

C. toward the floor
