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

Answer:

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

The gravitational force is Fg/16

Explanation:

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

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

Therefore,

Fg / 16

Answer 2

Answer:

1/16 th of the previous gravitational force

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
