Question

The acceleration due to gravity at the North Pole of Neptune is approximately 11.2m/s^2. Neptune has a mass 1.02 x 10^26 kg and radius 2.46x10^4 km and rotates once around its axis in a time of about 16h.

A) what is the gravitational force on a 4.40 kg object at the North Pole of Neptune!?

B) what is the apparent weight of this object at Neptune equator!? ( note that Neptunes surface is gaseous not solid so it's impossible to stand on it!?
