Question

(i) How does the force of gravitation between two objects change when the distance
between them is reduced to half?
(ii) At what position of earth, the value of acceleration due to gravity (g) becomes
maximum.​

Answer 1

Explanation:

1.According to the law of gravitation, the force of attraction acting between two bodies is given by, Thus, when the distance between the objects is reduced to half the gravitational force increases by four times the original force.

2.Where, g is the acceleration due to gravity on the surface of the earth. g' = g Thus acceleration due to gravity is least at the equator and maximum at the poles.

Answer 2

1- The force of gravitation between two objects is inversely proportional to the square of the distance between them therefore the gravity will become four times if distance between them is reduced to half.

2- Where G is the acceleration due to gravity on the surface of thr earth. g'=g, Thus acceleration due to gravity and maximum at the poles.
