## Homework Statement

Earth has the mass 6 · 10^24 kg and the orbit radius r = 1.5 · 10^11 m.

(a) Compute its de Broglie wavelength. (b) Apply de Broglie quantization condition

as in the case of the Hydrogen atom and compute the quantum number n for the

orbit of Earth. (c) What is the difference between the radius of nth and n + 1th

orbit?

## Homework Equations

lamba=h/p=h/mv

## The Attempt at a Solution

I am using the above equation to solve this but im stuck at getting the velocity of earth. I am completely stumped.
