Question

9) If the Earth shrinks to 50% of its real radius its mass remaining the same, the weight of a body on the Earth will a) decrease by 50% b) increase by 50% c) decrease by 25% increase by 300% 10) To project the rockets which of the follow- ing principle(s) is/are) required? a) Newton's third law of motion b) Newton's law of gravitation babu
​

Answer 1

Answer:

9A) a/c to question, The earth shrinks 50% of its real radius . hence, weight of body will be (1/4)th of weight of body when radius of earth is real

10A) Each Reaction have its equal and opposite reaction. so, option b is right. Newton's 3rd Law of motion.

Answer 2

increase by 300%
