A metallic rod of length `l` rotates at angular velocity `omega` about an axis passing through one end and perpendiuclar to the rod. If mass of electron is m and its charge is –e then the magnitude of potential difference between its two ends is
Options:
(a) `(momega^2l^2)/((2e))`
(b) `(momega^2l^2)/e`
(c) `(momega^2l)/e`
(d) None of these
