Gravitation | Energy Of Orbiting Satellite

Choose the correct alternatives : If the zero of potential energy is at infinity, the total energy of an orbiting satellite is negative of its kinetic/potential energy.

The gravitational potential energy of satellite revolving around the earth in circular orbit is 4MJ . Find the additional energy (in MJ ) that should be given to the satellite so that it escape from the gravitational field of the earth.

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

Assertion : A satellite can not be set on a stable orbit in a planet not passing through the earth's centre. Reason: For the orbital motion of satellite, the centripetal force is provided by gravitational pull of earth on satellite.

What would be the projections velocity of a satellite so that intersteller (interspace with no gravitation) velocity of the satellite becomes the orbital velocity when it is in the orbit at height of 10R from earth's surface, where R is the radius of the earth?

A satellite of mass m is revolving at a height R above theh sruface of Earth. Here R is the radius of the Earth. The gravitational potential energy of this satellite

The total energy of a circularly orbiting satellite is

Assertion: if an earth satellite moves to a lower orbit, there is some dissipation of energy but the satellite speed increases. Reason: The speed of satellite is a constant quantity.
