(part 1 of 2) Two identical conducting spheres are placed with their centers 0.49 m apart. One is given a charge of +1.5 x 10-8 C and the other a charge of -1.7 x 10-8 C. Find the magnitude of the electric force exerted by one sphere on the other. The value of the Coulomb constant is 8.98755 x 10° N - m²/C2. Answer in units of N. (part 2 of 2) The spheres are connected by a conducting wire. After equilibrium has occurred, find the electric force between them. Answer in units of N.
