A 2110-kg space station orbits Earth at an altitude of 551000 m. What is the magnitude of the force with which the space station attracts Earth?

The mass and mean radius of Earth are #5.98 * 10^24# kg and #6370000# m, respectively.

#1.757 × 10^4 "N"#

Explanation:

Both planet and space station will attract each other by same gravitational force (F). It is given by

#"F" = "GMm"/"d"^2#

Where,

  • G = Universal Gravitational constant
  • M = Mass of planet
  • m = Mass of space station
  • d = Distance between the satellite and centre of earth

#"F"= ("6.67 × 10"^-11 "Nm"^2//"kg"^2× "5.98 × 10"^24 "kg" × "2110 kg")/(551xx10^3 "m" + 637xx10^4 "m")^2#

#"F" = 1.757 × 10^4 "N"#

True or false? the gravitational force between two particles depends upon the medium between the two particles.
