Two identical small metal spheres are separated by 1.00 × 105 m and exert an 18.9-N repulsive force on each other. A wire is connected between the spheres and then removed. The spheres now repel each other, exerting a 22.5-N force. Assume both charges are positive.

1. Determine the total charge of this system.

q =______ (units)

2. Determine the charges of the spheres before the connection.

q1, q2 = ______ C
