A uniformly Charged Disc is rotating with constant angular velocity $\omega$ about it's edge 'P' . Then Find Ratio

$\displaystyle{\cfrac { { B }_{ p } }{ { V }_{ p } } \times { 10 }^{ 16 }}$.

Here ${ B }_{ p }{ \& V }_{ p }\quad$ means magnitude of Magnetic field strength and electric Potential at the edge P.

Details

$\bullet$ Assume that whole Experiment is doing in Vacuum.
$\bullet$ Use $\displaystyle{{ \cfrac { 1 }{ \sqrt { { \mu }_{ o }{ \epsilon }_{ o } } } =3\times { 10 }^{ 8 } }}$

$\bullet$ use $\omega =126\quad$ (All are in SI unit).
