when a metallic rod of length l is rotating about an a axis passing through its ends , electrons in the metallic rod are experiencing
centrifugal force mω2l as shown above .
 
where m is mass of electron , ω is angular speed of rotation , l is length of rod
 
workdone to move electron from left end to right end = Force × distance =  ( m ω2 l ) × l = ( m ω2 l2 )
 
Potential difference = Workdone / Charge
 
If electron charge is e , then we have  Potential difference = ( m ω2 l2 ) / e

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
