Answer 1

F=k(ne)(ne)/r^2
This the coulomb force.
n is the no of electrons transferred from one sphere to another.
Find the value of n from the data given.

We have to find the fraction of the electrons to be transferred. For that we require the total no of electrons in the 10g of sphere.
If Ma is the molar mass of silver.
Electrons in Ma grams= 6.022*10^23* 47
Electrons in 10g= 6.022*10^23*47*10/Ma
Let the scary expression on the right hand side be denoted by Q
Fraction of electrons transferred=n/Q
