NEET Physics Universal Law of Gravitation Assertion Reason Question
Assertion (A): The force of attraction between a hollow spherical shell of uniform density and a point mass situated outside the shell acts as if the entire mass of the shell is concentrated at its center. | Reason (R): The gravitational force follows an inverse square law with distance.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true as per the gravitational shell theorem, but the reason does not explain it; the explanation involves the symmetrical cancellation of perpendicular components of forces.
