Question

a satellite is revolving round the earth with orbital speed
v0 if it stops suddenly,the speed with which it will
strike the surface of earth would be-( ve=escape
velocity of particle n earth surface)

Total Energy of Satellite=-GMemRmv02R=GMemR2mv02=GMemREnergy on surface of Earth=-GMemR+12mv212mv2-GMemR=-mv02v2=-2v02+2GMeRv2=-2v02+ve2v=[ve2-2v02]

a satellite is revolving round the earth with orbital speed v0 if it stops suddenly,the speed with which it will strike the surface of earth would be-( ve=escape velocity of particle n earth surface)
