Both masses and their separation are doubled. The gravitational force between them?
AStays the same
BIs doubled
CBecomes 4 times
DBecomes halved
Answer & Solution
Correct answer: A. Stays the same
Masses give a factor 2x2 = 4 in the numerator, and the distance gives 2^2 = 4 in the denominator, so F is unchanged.
