Rotation about edge!

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).
