An artificial satellite of earth releases a packet. If air resistance is neglected, the point where the packet will hit will be?
Correct answer: D. it will never reach earth
- A. Behind
- B. Ahead
- C. Exactly below
- D. it will never reach earth
Explanation
Here is the explanation of the correct optionFc = mv2/rThe satellite will move in a circular orbit. When the packet is released it retains the tangential velocity of satellite.The packet will know act as a free falling body it will continue to follow a trajectory determined by initial tangential velocity and gravitational acceleration.The packet retains the horizontal velocity of the satellite upon the release and because no horizontal forces act on it will continue to move horizontally at the same speed as satellite.So it will revolve the earth like the satellite

About Satellite Motion and Orbital Velocity
Satellite motion uses gravitational force as the centripetal force required for circular orbit, giving relationships among orbital radius, period and orbital velocity. Questions cover geostationary conditions and weightlessness, while distinguishing orbital velocity, escape velocity and the satellite's tangential speed.

An artificial satellite orbiting around the earth does not fall down because the attraction of the earth
Suppose that thomass and radius of the Moon changes to 7.35 x 10^22 kg and 1.7 × 10º m respectively. The escape velocity of the Moon will then be(Note: The value of Gravitational constant is 6.63 x 10^-11 Nm²/kg².)
For the purpose of oceanography and meteorology, Pakistan has launched a Remote Sensing Satellite System (RSSS) at an altitude of 7 x 10^5 m above the ground station.At the time of launch, the orbital velocity of the artificial satellite was calculated as(Note: The value of gravitational constant, mass and radius of Earth are 6.67 x 10" Nm³/kg.5.9 x 10 kg and 6.3 × 10º m respectively.)
