Two plastic spheres, each carrying charge uniformly distributed throughout its interior, are initially placed in contact and then released. One sphere has a diameter of 58.0 , a mass of m1= 45.0g , and contains -10.0 uc of charge. The other sphere has a diameter of 41.0 , a mass of m2= 140.0g and contains -30.0 uc of charge. Assume that no other forces are acting on them.
A. Find the maximum speed achieved by the sphere of mass 45.0g.
