#2a. Determine the magnitude of the force between two point charges, Q₁ = -650e located at (-4.60 cm, +3.10 cm) and Q2 = -458e located at (+2.50 cm, -7.60 cm). Give your answer in the form "a.bc x 10^ N". Note that e is the fundamental electric charge. 650e is simply 650 x e (the fundamental electric charge). similarly 458e is simply 458 x e (the fundamental electric charge).
