An electron rotates in a circle around a nucleus with positive charge `Ze`. How is the electrons'velocity realted to the radius of its orbit?

An electron revolvles in a circular orbit around a nucleus of charge Ze. How is the electron velocity related to the radius of its orbit?

An electron is placed in an orbit about a nucleus of charge +Ze. It requires 47.2 eV energy to excite an electron from second Bohr orbit to third Bohr orbit. What is the value of Z?

Electrons revolve around the nucleus in definite orbits called .........

An electron orbiting around a nucleus has angular momentum L. The magnetic field produced by the electron at the centre of the orbit can be expressed as :

An electron orbiting around a nucleus has angular momentum L. The magnetic field produced by the electron at the centre of the orbit can be expressed as :

Two electrons of mass m each orbit around a nucleus of mass 80m such that both the electrons are always at two diametric opposite points in their single circular orbit around the nucleus. The ratio of gravitational force between two electron i=and the nucleus to that between the two electron is K . What is the value of K?

A single electron orbits around a stationary nucleus of charge +Ze. It requires 47.2 eV to excite the electron from the 2^"nd" to 3^"rd" Bohr orbit. Find atomic number 'Z' of atom .
