Solve the following:
Forces: Newtons laws of motion. Find the magnitude of a gravitational force; difference in mass of robot on two planets
Q: 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.
Q: 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?
