Question

Find gravity of a planet with respect to a satellite

Answer 1

Hey mate
here is your ans

at an altitude of hundred kilometre you will be so high that you would be six black spy and stars if you look up words if you do get a satellite to this height and released it it would still fault towards the earth because the force of gravity is nearly the same as it is at the earth surface however if the satellite is given speed in any direction horizontal to the surface to the earth it will travel further before its hits the earth it is given enough speed it will travel so far that as it curves toward the earth it will miss the earth altogether at just the right rate it will move around the earth in a circular motion this type of motion and the path that a satellite moves is called in orbit .close to the earth at an altitude of a 100km a satellite needs to be moving at 8km per sec (28000km/h) to stay in orbit at higher altitude satellite do not need to be traveling as fast television communication satellites are at a higher altitude of 36000km and only needs to travel at 3 km/s (12000 km/h).the moon is 360000 km from the earth and only needs to be travelling at 1 km/s you stay in orbit around the earth .

thank you ..
