In the Bohr model of the atom, atomic electrons approximatately 'orbit' the nucleus. The hydrogen atom consists of a proton of mass 1.67 × 10-27 kg and an orbiting electron of mass 9.11 × 10-31 kg. In one of its orbits, the electron is 5.3 × 10-11 m from the proton. What is the mutual attractive gravitational force between the electron and proton

Explanation:

Mass of a proton,

Mass of an electron,

The distance between the electron and the proton is,

We need to find the mutual attractive gravitational force between the electron and proton. The gravitational force is given by :

Where G is the universal Gravitational constant

So, the force between the electron and proton is .
