Vedclass · Answer

(D) The gravitational force is the dominant force on a cosmic scale because it is always attractive and acts over long distances between massive objects,whereas the Coulomb force (electrostatic force) is often neutralized by the presence of both positive and negative charges in matter.Therefore,the Assertion is incorrect.Furthermore,the gravitational force is significantly weaker than the Coulomb force at the microscopic level (e.g.,between two electrons),but the Reason states that the Coulomb force is weaker than the gravitational force,which is incorrect.Thus,both the Assertion and the Reason are incorrect.

Assertion : The Coulomb force is the dominating force in the universe.
Reason : The Coulomb force is weaker than the gravitational force.
