Gravitaional potential energy

Question

A space station is set up in space at a distance equal to earth’s radius from earth’s surface. Suppose a satellite can be launched from space station. Let V₁ and V₂ be the escape velocites of the satellite on earth’s surface and space station respectively. Then

Easy

A

V₂ = V₁
B

V₂ < V₁
C

V₂ > V₁
D

No relation

Solution

$\large \fn_cm \large V_1=\sqrt{\frac{2GM}{R}}\\\\ V_2=\frac{2GM}{(2R)}=\sqrt{\frac{GM}{R}} \\\\ \therefore \sqrt 2 =\frac{V_1}{V_2}$
