Answer:
Atoms in a metal sphere , .
To Find :
If one electron is removed from 0.1% atom, what will be the charge on the sphere .
Solution :
Total charge removed from the sphere is given by :
q=-4 x 10^23 x 0.1/100 x 1.6 x x 10^-19
q=-4 x 10^20 x 1.6 x10^-19
q=-64 C
Therefore , to maintain conservation of charge the same positive charge will stay in the sphere .
So , the charge on the sphere will be .
Hence , this is the required solution .
