Question

Two identical small metal spheres withqi > 0 and attract each other with a force of magnitude 81 mN when separated by a distance of 2.65 m. r2 27 m 21 F12 1 42 2.65 m The spheres are then brought together until they are touching, enabling the spheres to attain the same final charge q. 29 After the charges on the spheres have come to equilibrium, they spheres are separated so that they are again 2.65 m apart. F21 F12 2.65 m Now the spheres repel each other with a force of magnitude 12.15 mN What is the final charge on the sphere on the right? The value of the Coulomb constant
Question (part 2 of 2) What is the initial charge qi on the first sphere? Answer in units of C. Your response.
