Chapt. 22Electric Charge177a) Given that copper’s atomic mass is 63.5 in atomic mass units (i.e., in units of 1.66×10−27kg), how many copper atoms are there in the penny?HINT:If you have 10 kg ofeggs and each egg weighs 50 g, then you how many eggs?b) Given that a copper atom has 29 protons (i.e., atomic number Z=29), how much grosspositive charge in Coulombs does the penny have?c) Imagine (contrafactually as they say in Washington) that the absolute value of theelementary proton charge was 1.000001 times larger than the absolute value of theelementary electron charge (i.e., there was a fractional charge difference of (δe/e) = 10−6),what would be the force between two pennies a distance 1 meter apart assuming that thepennies would be neutral if there were no fractional charge difference.d) Is a charge difference between proton and electron of the order suggested in the part (c)question likely?
