Assertion: In universe, gravitational force dominates in long distance and electric force dominates in short distance.

Reason: For gravitational force ∝ (mass) 2 distance 2\propto \frac{\text { (mass) }^2}{\text { distance }^2} and electric force ∝ charge 2 distance 2\propto \frac{\text { charge }^2}{\text { distance }^2}
View answer and explanation
Correct option: A
Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
Option A is correct. Gravitational force dominates over long distances due to the large masses of celestial bodies, while electric force dominates at short distances due to the presence of charges. The reason correctly explains this.
