In a hypothetical concept, electron of mass `m_(e)` revolves around nucleus due to gravitational force of attraction between electron and proton of mass `m_(p)`. If the radius of circular path of electron is r, then the speed of electron is

Why are electrons revolving around the nucleus?

In a hydrogen atom, the centripetal force is furnished by the coloumb attraction between electron and proton. If a_(0) is the radius of first state orbit and permittivity of vacuum is in_(0) , then the speed of the electron is.... [m = mass of electron, e = charge on electron]

The force of attraction between an electron revolving around the nucleus and the nucleus is ______ force.

If an electron of charge (-e) and mass m_(e) revolves around the nucleus of an atom having magnetic moment M_(e) , then angular momentum of electron is

At what speed should the electron revolve around the nucleus of a hydrogen atom in order that it may not be pulled into the nucleus by electrostatic attraction ? Take the radius of orbit of an electron as 0.5Å , the mass of the electron as 9.1xx10^(-31) kg and charge as 1.6xx10^(-19)C .
