Questions
An artificial satellite is revolving around the earth in a circular orbit. Its velocity is one third of the escape velocity. Its height from the earth’s surface is (in km)
detailed solution
Correct option is A
v=ve3 GMR+h=132GMR Squaring on both sides we get ⇒GMR+h=192GMR ⇒9R=2R+2h ⇒7R=2h ⇒h=7R2=7×6400km2=22400kmTalk to our academic expert!
