Question

a) How does the force of gravitation between two objects change when distance between them is

reduced to 1/4th

. b) How does the value of g vary with the mass of the object?​

Answer 1

Explanation:

a) Since the force of gravitation between two objects is inversely proportional to the square of the distance between them, the gravity will become eight times if distance between them is reduced to one - fourth.

b) The mass of the object doesn't change but the weight may change if there is any change in the value of g. The mass remains constant throughout until we physically change the mass of the object under observation.
