AS Level Physics question STUCK {REP RETURNS}
metal sphere carries a charge of -20C and is brought into contact with an identical sphere with charge of +36C.
How much charge is there when they touch? i put 16C
How much charge on each sphere when moved apart?
How many electrons does each sphere now carry?
No clue on the last 2 questions

1st question: 16C is correct
2nd question: notice that the spheres are IDENTICAL. they have the same charge density so they should have the same charge which is 8C
3rd question: 1eV = 1.6*10^-19C so 8C=8/(1.6*10^-19) eV
eV is equal to the number of electrons
