Ответ:
7.9 x 10^-3 N attractive in nature
Explanation:
QA = 13.5 nC = 13.5 x 10^-9 C
QB = - 22.05 nC = - 22.05 x 10^-9 C
d = 1.84 cm = 0.0184 m
Let the electric force on object A is F.
By use of Coulomb's law in electrostatics
F = K x QA x QB / d^2
F = (9 x 10^9 x 13.5 x 10^-9 x 22.05 x 10^-9) / (0.0184 x 0.0184)
F = 7.9 x 10^-3 N attractive in nature

Hi!
So I don't know what the heck net force is, but I think the box would move right because there is more force moving to the right.
