Choose the correct alternative:
(a) If the zero of potential energy is at infinity the total energy on orbitin g satellite is negative of its kinetic/potential energy.
(b) The energy required in rocket an orbiting satellite
out of earth gravitation influence is more or less than the energy required to project a stationary object at same height (as can the satellite) out of earth influences.


(a) Kinetic energy, (b) Less.
