In the Bohr model of hydrogen atom the electron revolves around the nucelus at the rate of `36 xx 10^16` revoltuions per minute. Calculate the average current at a point on the orbit.

In Bohr's model of hydrogen atom, the electron circulats around nucleus on a path of radius 0.53A^@ at a frequency of 6.8 xx 10^15 rev//sec . Calculate magnetic field induction at the centre of the nucleus. What is the effective magnetic dipole moment?

An electron in an atom revolves around the nucleus in an orbit of radius 0.5 angstrom. Calculate the equivalent magnetic moment if frequency of revolution is 10^10 MHz .

The electron in the first orbit of hydrogen atom revolves round the nucleus in a circular orbit of radius 0.5 overset@A with a speed 2.18xx10^(6) m/s . What is the centripetal force acting on the electron ? (Mass of electron = 9.1xx10^(-31) kg).
