omar rubs a balloon with wool giving the ballon a charge of -8.9*10^-14 C. What is the force between the ballon and a metal sphere that is charged to 25C and is 2 km away?

A small object has a mass of 3.0 x 10 kg and a charge of where there is an electric field. When released, the object experiences an acceleration of 2.5 x 10° m/s? in the direction of the + x- axis. (a.) Find the magnitude and direction of the net force. (Hint: Fnet = ma) (b.) Determine the magnitude and direction of the electric field. 34 µC. It is placed at a certain spot

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. ROJS a) What is the final charge on the third sphere?60 SS μC sf60 s60 s ssf60 ssfo ssf603 60 ssf60 ssi
