Question

If the distance between two masses is increased by a factor of 2, by what factor
would the mass of one of them have to be altered to maintain the same
gravitational force?

Answer 1

Answer:

Gravitational force is given by:

F=G× d^2

m×M

Distance between two masses is increased s.t. new distance is D= 5 d

New gravitational force F

1

=F

Let on of the mass is changed to m

1

so as to maintain the same gravitational force.
