Two forces applied simultaneously to the same point have the same effect as a single equivalent force. The resultant force can be found by constructing a parallelogram with the initial force vectors forming two adjacent sides. The diagonal of the parallelogram gives the resultant force vector. electric field components of Coulomb force moving a charge
