Question

if the distance between two masses be increased by a factor 6, by what factor would the mass one of them have to be altered would this be increased or decrease in mass

Answer 1

Answer:

The gravitational force b/w two bodies having mass M and m and separated by a distance r is denoted as

1.F = GMm/r2

2.When r is increased by factor 4 , then its effect will be indirectly proportional and in square , means G force will lessened by 16 times ….

3.For compensating this, one of the body needed to be heavier by 16 times

Hence answer is 16
