Two spherical conductors are separated by a distance much larger than either of their radii. Sphere A has a radius of 46.5 cm46.5 cm and a net charge of −95.5 nC,−95.5 nC, whereas sphere B, which is initially neutral, has a radius of 94.4 cm.94.4 cm. The two spheres are then connected by a thin metal wire. What is the charge on sphere B after equilibrium has been reached?
