Concept explainers
The ratio of the electrostatic force to the gravitational force between the electron and the proton.
Answer to Problem 60A
Explanation of Solution
Given:
It is known that,
The mass of electron,
The mass of proton,
The charge on proton,
The charge on electron,
Formula used:
The electrostatic force between two charges,
Where,
And, Law of Universal Gravitation,
Where,
It is known that the value of gravitational constant is,
Calculation:
Let the distance between the electron and proton be
Then, the magnitude of the electrostatic force between the electron and proton is,
And, the gravitational force between them is,
Then, the ratio of the electrostatic force to the gravitational force between electron and proton will be,
Conclusion:
Hence, the ratio of the electrostatic force to the gravitational force between electron and proton is
