Assetrion: The coulomb force is the dominating force in the universe.
Reason: The coulomb force is weaker than the gravitational force.

Options

A. If both assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both assertion and reason are true but Reason is not the correct explanation of the Assertion.
C. If Assertion is true, but the Reason is false.
D. If both assertion and reason are false

Answer

d

Explanation

The electrostatic force between the two protons is nearly `10^(36)` times the gravitaional force between them. The electrostatic force between the two electrons is nearly `10^(43)` times the gravitaional force between them. The electrostatic force between a proton and an electron is nearly `10^(39)` times the gravitional force between them. Gravitational force is the dominating force in nature and not Coulomb's force. Gravitational force is the weaker force. Also, Coulomb's force `gt gt `gravitational force.
