On earth, two parts of a space probe weigh 16900 N and 3880 N. These parts are separated by a center-to-center distance of 17.3 m and may be treated as uniform spherical objects. Find the magnitude of the gravitational force that each part exerts on the other out in space, far from any other objects.
The mass of a robot is 4420 kg. This robot weighs 2620 N more on planet A than it does on planet B. Both planets have the same radius of 3.45 x 107 m. What is the difference MA -MB in the masses of these planets?
First, we need to find the mass of each part. Recall F = mg where I will assume g = 9.81m/s
16900N = m1 (9.81)
m1 = 1723kg
3880N = m2 (9.81)
m2 = 396kg
Now far away from ...
The solution carefully explains the problem in a step by step process which results in the answers.
