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

Answer:
Given :mass of satellite =1000 kg
mass of earth =6 ×10 ^-11kg
distance =40 000 km =40000000m
G=6.67×10 ^-11Nm^2kg^-2
to find : force
solutions:F=Gm1m2/r2
6.67×10
^-11×1000×6×10^24/40000000^2
6.67×6×10^16/16×10^14
6.67×6×10^2/16
=250.1N
Ans:gravitational force exerted is 250.12N
Hope it helps you!
