The net force is the sum of all of the forces on the charged object.  The only forces acting on the charged object in this simulation are the electric and magnetic forces.  Hence, in this simulation,

.

You indicated that the direction of the electric field at point A is direction 1 and the direction of the magnetic field is direction 5.  You did not indicate whether the electric or the magnetic force is larger. 

• If the electric force is larger, then the net force points in the same direction as the electric force (i.e., direction 1).
• If the magnetic force is larger, then the net force points in the same direction as the magnetic force (i.e., direction 5).
• If the electric and magnetic forces have the same magnitude, then the net force is zero.

In summary, if it is not known whether the electric or magnetic force is larger, then adding them does not reveal the direction of the net force. 

Remember, however, that the net force is related to the acceleration through Newton’s Second Law:

.

Newton’s Second Law is a vector equation.  Since the mass is a positive scalar, the two vectors in the equation must have the same direction.  Hence, the direction of the net force, , is the same as the direction of the acceleration, .  Once the direction of the net force is known, then you can determine whether the electric or magnetic force is larger.  Which is larger when the object is at point A?
