JEE Main 2016 — Gravitation Question with Solution
From: JEE Main 2016 (Offline)
Question
A satellite is revolving in a circular orbit at a height from the earth's surface (radius of earth ). The minimum increase in its orbital velocity required, so that the satellite could escape from the earth's gravitational field, is close to : (Neglect the effect of atmosphere.)

Show full solutionCorrect option: D
Correct answer
D
Step-by-step explanation
Orbital velocity of satellite,
= [ As then R + h = R ]
= [ As ]
Escape velocity
= [ As ]
The minimum increase in its orbital velocity required to escape from the earth gravitational field
= [ As then R + h = R ]
= [ As ]
Escape velocity
= [ As ]
The minimum increase in its orbital velocity required to escape from the earth gravitational field
