An early planetary model of the hydrogen atom consisted of a 1.67 X 10-27 kg proton in the nucleus and a 9.11 X 10-31 kg electron in orbit around it at a distance of 5.0 X 10-11 m. In this model, what is the gravitational force between a proton and an electron?

The gravitational force between proton and an electron is N

Explanation:

Given:

Mass of proton kg

Mass of electron kg

Separation between electron and proton m

According to the gravitational law,

Where = gravitational constant.

    N

Therefore, the gravitational force between proton and an electron is N
