Answer to Question #271665 in Physics for Almas Bashir

Question

Calculation of Bohr's atomic model of velocity of electron in nth orbit.

Answer 1

The velocity of the electron in the n orbit of a hydrogen atom is calculated using the formula

$$v=\frac{nh}{2\pi mr}$$

where n is the number of orbits, h is the Planck’s constant, m is the mass of an electron, r is the radius of the orbit. This formula is derived from the de Broglie Equation of angular momentum.
