A launching vehicle carrying an artificial satellite of mass 'm' is set for launch, on the earth's surface. If the satellite is intended to move in a circular orbit of radius '7R', the minimum energy required to be spent by the launching vehicle is: (G= Universal gravitation constant, M and R be the mass and radius of the earth) - VgyanHub
