Question -
Answer -
Mass of the Earth,┬аM┬а= 6.0├Ч 1024┬аkg
Mass of the satellite,┬аm┬а=200 kg
Radius of the Earth,┬аRe┬а= 6.4 ├Ч 106┬аm
Universal gravitational constant, G = 6.67 ├Ч10тАУ11┬аNm2kgтАУ2
Height of the satellite,┬аh┬а=400 km = 4 ├Ч 105┬аm = 0.4 ├Ч106┬аm
Totalenergy of the satellite at height┬аh
Orbital velocity of the satellite,┬аv┬а=
Total energy of height,┬аh
The negative signindicates that the satellite is bound to the Earth. This is called bound energyof the satellite.
Energy required to sendthe satellite out of its orbit = тАУ (Bound energy)
