Best ResponseYou've already chosen the best response.0dw:1444155846805:dw the 3 charges should form an equilateral triangle of side \(\sqrt{3}\). there is also quite some symmetry in the set up. the force between the charge at the top and each of the other two charges will follow Coulumb's Law. For each pair, \(\large F = k \dfrac{q^2}{r^2}\) where \(\large q = 2.5 \mu F, r = \sqrt{3} \) in the leftright direction, these force will cancel  due to symmetry. in the updown direction we can add their **updown components** so the overall force is \(\large F_{net} = 2 \times k \dfrac{q^2}{r^2} \cdot \sin 60^o\)
