A missile is launched with a velocity less than the escape velocity. The sum of its kinetic and potential energy is
Text Solution
Verified by ExpertsThe correct answer is:
B
If missile 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.
