Two small conducting spheres are identical except that sphere x has a charge of -10 micro coulombs and sphere y has a charge of + 6 micro coulombs . After the spheres are brought in contact and then separated,what is the charge on each sphere ,in micro coulombs ?

Answer 1

the charge is evenly divided among the spheres
Total charge = -10+6 = -4 *10^-6 C
so each has
-2*10^-6 C
