AIIMS 2002 Physics Orbital and Escape Velocity MCQ Question
Type: MCQ-conceptual-Medium-Class 11
If v₀ be the orbital velocity of a satellite in a circular orbit close to the earth's surface and vₑ is the escape velocity from the earth, then relation between the two is
A
v₀ = vₑ
B
vₑ = √3v₀
C
vₑ = √2v₀
D
vₑ = 2v₀
Correct Answer
Option C
Detailed Explanation
Orbital velocity of satellite = v_0 and escape velocity from the earth = v_e. We have orbital velocity (v_0) = √gR and escape velocity (v_e) = √2gR.
