The differences between the two methods of charging a body are as follows:

a) Charging a body by conduction is done by touching a charged body, whereas no touching is needed to charge a body by induction.

b) In charging by conduction, charge moves from charged body to uncharged body, whereas in charging by induction no charge flows from charged body to the uncharged body.

c) Some charge is lost in charging by conduction, whereas there is no loss in any charge in charging by induction.

Find out the no. of moles of copper in the coin first which would be 3/63.5 now multiply it by 6.022*10^23 u will get the no. of atoms now one atom has 29 electron and 29 proton
