three identical metallic conducting spheres carry the following charges: q = +5.8 μC, q = +7.4 μC, and q = −7.6 μC. The spheres that carry the charges q and q 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 q. What is the final charge on the third sphere?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
