Two copper balls, each weighing 10g are kept in air 10 cm apart. If one electron from every 106 atoms is transferred from one ball to the other, the coulomb force between them is (atomic weight of copper is 63.5)
We know, Charges can be transferred from one body to another.
Number of atoms in the given mass =
Number of electrons transferred between the balls =
Magnitude of charge gained by each ball =
Force of attraction between the balls =
