A satellite is revolving around the earth with 
of total mechanical energy. The energy needed to throw it out of the Earth's gravitational field is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
An object bound to Earth's gravitational field must have negative potential energy (here 
at infinity to be taken zero). If the total mechanical energy of an object is positive, then it will definitely leave the Earth's gravitational field.
