Question

Please show method and answer

A submarine of mass 200 kg is sent into a newly discovered "liquid" planet , i.e. the
planet is a spherical mass of liquid with a mass M = 8.00 x1024 kg and a radius of
R=1.17 x10' m. Assume that the liquid has uniform density throughout the planet.
What is the gravitational force on the submarine when its distance from the center
of the planet is r=0.4R (in Newtons)? G = 6.67 x 10-11 N. m2/kg²
