Answer:Mass of satellite = 1000kg
Mass of Earth = 6*10^-11 kg
Distance = 40000 km
Gravity constant = 6.67* 10^-11 Nm^2 kg^-2
Note: change km into m
= 40000000m
Force = gravity constant * mass 1 * mass 2/
distance ^ 2
Force = 6.67*10^-11 * 1000 * 6* 10^ 24/
40000000^ 2
Force = 6.67*6* 10^ 16/ 16*10^ 14
Force = 6.67 * 6 * 10^ 2/ 16
Force= 250.12 N
