Question

1kg of electron are lump together to form solid charged sphere. Total magnitude of charge on the sphere
is ??

Answer 1

Answer:

The mass of an electron is 9.11×10−31 kg, so you need 1.10*10^30 electrons to get a mass of 1 kg. Their total charge will be 1.10*10^30 times that of a single electron (−1.61×10−19 Coulomb), which is -1.77*10^11 Coulomb.
