Question

Object A is metallic and electrically neutral. It is chargedby inductor so that it acquires a charge of -3.0x10-6C. Object B is identical to object A and is also electricallyneutral. It is charged by induction so that it acquires acharge of +3.0x10-6 C. Find the difference in massbetween the charged objects and state which has the greatermass.

Object B has the greater mass due to having more electrons Ibelieve, but how would I determine the difference?



Part 2.

Water has a mass per mole of 18.0g/mol, and each water molecule(H20) has 10 electrons (a) How many are there in oneliter (1.00x10-3m3 )of water? (b) Whatis the net charge of all these elements?

Explanation / Answer

There are just two steps to the solution.    divide the total charge difference ( total diff =6*10-6C ) by the charge per electron to get the total no. ofelectrons that would cause the mass difference. the negative body would have mass greater by : (6*10-6/1.602*10-19)*9.1*10-31kg = 3.40824*10-17 kg
