The result is an unbalanced force to the right or acting in the a-axis.

Explanation:

For the first diagram, we propose a sum of forces on the X & y axes and include these forces arithmetically, i.e. the upward forces with a positive sign and the downward forces with a negative sign. Forces to the right with positive sign and forces to the left with negative sign.

ΣFx = 0

+ 1 +3 = Fx

Fx = 4 [N] (units of Newtons]

ΣFy = 0

-2 + 2 = Fy

Fy = 0

Therefore the result is an unbalanced force to the right or acting in the a-axis.

c) up is the direction the magnetic force is acting on the charge.
