A metal sphere A has charge Q. Two other spheres, B and C, are identical to A except they have zero net charge. A touches B, then the two spheres are separated. B touches C, then those spheres are separated. Finally, C touches A and those two spheres are separated. If sphere C is grounded when it is touching B, but C is not grounded at any other time. What is the final charge on each sphere?
Sphere A = ____Q
Sphere B= ____Q
Sphere C= ____Q
