Assertion (A) Electromagnetic force is enormously strong as compared to gravitational force. Yet, gravity dominates in the large-scale phenomena (e.g. formation of galaxies). Reason \((R)\) Existence of positive and negative charges make matter mostly electrically neutral. Which of the following is true?
- A Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\)
- B Both \((A)\) and \((R)\) are true, but \((R)\) is not the correct explanation of (A)
- C (A) is true, but \((R)\) is false
- D (A) is false, but \((R)\) is true
Answer & Solution
Correct Answer
(A) Both \((A)\) and \((R)\) are true and \((R)\) is the correct explanation of \((A)\)
Step-by-step Solution
Detailed explanation
Both A and \(\mathrm{R}\) true and \(\mathrm{R}\) is the correct explanation of A. "Although the electromagnetic force is far stronger than gravity, it tends to cancel itself out within large objects, so over the largest distances (on the scale of planets and galaxies), gravity…
