Questions
A missile is launched with a velocity less than the escape velocity. The sum of its kinetic and potential energy is
detailed solution
Correct option is B
If missile is launched with escape velocity then it will escape from the gravitational field and at infinity its total energy becomes zero.But if the velocity of projection is less than escape velocity, then sum of energies will be negative. This shows that attractive force is working on the satellite.Talk to our academic expert!
