Question

Multiplication of electron velocity and radius for a
orbit in an atom is :-
(1) Proportional to mass of electron
(2) Proportional to square of mass of electron
(3) Inversely proportional to mass of electron
(4) Does not depend upon mass of electron​

Answer 1

Explanation:

the multiplication of electron velocity and radius for an orbit in an atom is inversely proportional to mass of electron. Thus, the correct option is (C) inversely proportional to mass of electron. Note: The equation shows that the values of energy and angular momentum of an electron are quantized
