Question

if the separation distance between the moon and the planet is increased by a factor of 4 then the force gravitational is

Answer 1

1/16 th of the previous gravitational force

Step-by-step explanation:

F =G (m1 x m2)/ r^2

r= distance between moon and planet

if r1 = 1 and r2= 4 1^2 / 4^2= 1/16

Answer 2

Fg = (G * m1 * m2) / r^2

The gravitational force is Fg/16

Step-by-step explanation:

Fg = (G * m1 * m2) / (4r)^2

Fg = (G * m1 * m2) / 16r

Therefore,

Fg / 16
