Dear Sir/Madam,
In the exam decoded section of law of gravitation video, one of the questions and its answer is if the distance between the sun and the earth doubles, the gravitational force between them will be 1/4.
Later, a female exam expert says that the gravitational force obeys inverse square law and if the distance between two objects halved, the force becomes 1/4.
Dr. Chandralekha's exam decoded answer is opposite to this exam expert. Both differences in distances gave the same magnitude of force (as I typed in bold). Please re-check this video.
Thank you

How do we solve complex problems related to the gravitational force, for example.. Calculate the gravitational force of attraction between the earth and moon when the mass of earth and given. I know the formula can be applied but how do we solve further because the calculations get quite complex and I personally, waste a lot of time myself for solving such sums in my exam paper. Urgent, pls reply fast.
