Questions
At what height from the surface of earth , the total energy of satellite is equal to its potential energy at a height 2R from the surface of earth(R= radius of earth)
detailed solution
Correct option is B
TE=PE ⇒−GMm2R+h'=−GMmh+R∵TE=−GMm2r,PE=−GMmrwhere r=R+h ⇒12R+h'=12R+R ⇒3R=2R+2h' ⇒R=2h' ⇒h'=R2Talk to our academic expert!
