a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The gravitational force of attraction between two masses is inversely proportional to the square of the distance between them, as per Newton's law of universal gravitation. The universal gravitational constant is defined as 6.672 × 10 –11 N m 2 kg –2, and the force due to a hollow shell can be treated as if concentrated at its center. The resultant force is calculated using vector addition based on the principle of superposition.
