a. An electrically neutral penny, of mass 3.11 g, contains equal number of positive and negative charges. Assuming the penny is made of pure copper, what is the total positive (or negative) charge within a penny? Atomic mass of copper = 63.5 g/mol N. = 6.02 x 10" atoms / mol (Avogadro's number) 2010 CNADA Atomic Number of Copper = 29 protons/atom NOTE: you don't necessarily need chemistry for this.Dimensional analysis!!! b. Suppose the positive and negative charges could be isolated into two bundles and separated by a distance of 1.00 km. What would the force of attraction between the bundles be?
