The mutual force of gravitational attraction between two masses is 500 N. a) lf the masses are moved five times as far apart, what is their new mutual force of gravitational attraction? b) lf the masses are moved five times closer, what is their new mutual force of gravitational attraction?

If the gravitational field constant on the surface of the moon is 1.6 N/kg, what is the force of gravity acting on the two objects from 1) if they were on the moon?

Please answer the question and subquestions entirely. This is one single question. According to the official guideline, I can ask two subquestions! Thank you!   1) Two point masses are placed 10.0 cm apart and attract each other with a force of 10.0 N. Find the force of gravitational attraction between the masses when they are placed 5.00 cm apart.     3.00 N     4.50 N     20.0 N     40.0 N a) The radius of the orbit of a certain asteroid is four astronomical units. What is the period (in years) of this asteroid?     2 years     4 years     6 years     8 years b) A satellite is orbiting the earth at an altitude where the acceleration due to gravity is 8.70 m/s 2. What is its speed?     2.65 x 103 m/s     7.45 x 103 m/s     7.68 x 103 m/s     7.91 x 103 m/s

The planet and its moon gravitationally attract each other. Rank the forces of attraction between each pair from greatest to least. To rank items as equivalent overlap them.
