Consider two isolated masses M1 = m and M2 = 2m, if F is the modulus of the gravitational force acting

on mass M1, what is the modulus of the gravitational force acting on mass M2?

A) F

B) 2F

C) -F

D) -2F

E) 1.5F

Hi!

answer is A), i thought it would be B)? Whats the steps?

hi! gravitational force value doesn’t change! the weight does but remember they’re asking for the value as a MULTIPLE of the gravity modulus (they’re asking whether the constant changes). Again it’s an issue with the translation, its confusing you with F=mg I believe.

Oh of course i forgot about that!!! It absolutely confused me!
