Part A How many excess electrons must you add to an object to give it a charge of -4.00?C? Part B How many excess electrons must you add to an object to give it a charge of -8.50nC?
Explanation / Answer
a)
N=Q/e= 4*10-6/(1.6*10-19)
N=2.5*1013 electrons
b)
N=Q/e= 8.5*10-6/(1.6*10-19)
N=5.3125*1013 electrons
