Assertion Newton's law of gravitation resembles Coulomb's law of electrical forc
Assertion Newton's law of gravitation resembles Coulomb's law of electrical forces. Reason Coulomb's law has the product of two charges in place of the product of the masses, and the electrostatic constant in place of the gravitational constant.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Newton's law of gravitation and Coulomb's law of electrical forces are both inverse-square laws. The assertion correctly notes their resemblance. The reason correctly identifies the analogous roles: charges in Coulomb's law replace masses in Newton's law, and the electrostatic constant replaces the gravitational constant. Thus, the reason explains why the laws resemble each other.
