Choose the correct alternative : (a) If the zero of potential energy is at infinityn the total energy of an orbiting satellite is negative of its kinetic/potential energy. (b) The energy required to launch an orbiting satellite out of earth's gravitational influence is more/less than the energy required to project a stationary object at the same height (as the satellite) out of earth's influence.

1.	Choose the correct alternative : (a) If the zero of potential energy is at infinityn the total energy of an orbiting satellite is negative of its kinetic/potential energy. (b) The energy required to launch an orbiting satellite out of earth's gravitational influence is more/less than the energy required to project a stationary object at the same height (as the satellite) out of earth's influence.
Answer» Solution :`implies` (a) The total ENERGY of an orbiting satellite is negative of its kinetic energy. (b) The energy required to LAUNCH an orbiting satellite out of earth.s gravitational influence is LESS than the energy required to project a STATIONARY object at the same height out of earth.s influence.
