Expert Answer
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
