2. Three point-like charges are placed as shown in the figure, 1₁ = T2 = 52.0 cm. Find the magnitude of the electric force exerted on the charge q₁. Let q₁ = -2.50 μC, q2 = -3.40 µC, 93 = -3.90 μC. N ₁ ₂ 93

1. Three identical metallic conducting spheres carry the following charges: 91 = +5.00 μC, q2 = +1.40 µC, and 93 -9.20 μC. The spheres that carry the charges 9₁ and 92 are brought into contact. Then they are separated. After that, one of those two spheres is brought into contact with the third sphere that carries the charge 93; those two are then separated as well.
