The gravitational force between 2 objects is F . If masses of both the objects are halved without changing distance between them , then the gravitational force would be

Answer 1

You can figure things like this yourself as follows:
F = k(m1*m2)d^2 so let's assume m1 and m2 are 2 each and d is 2. So
F = k(2*2)/2^2 = k*1 or 1k.
Now half m1 and m2 so each is 1. Then
F = k(1*1)/4 = k*1/4 or k/4.
So the factor between 1K and k/4 is ?
