Question

if escape velocity and orbital velocity of a satellite for Orbit close to the Earth's surface then these are related by​

Answer 1

Answer:

The ratio of the escape velocity to the orbital velocity is $\sqrt 2$.

Explanation:

The minimum velocity given to an object so that it escapes from the earth's gravitational pull is called escape velocity.

The formula of the escape velocity is

$v=\sqrt\frac{2GM}{R}$

The velocity of an object in the orbit around the earth is called orbital velocity.

The formula of the orbital velocity is

$v=\sqrt\frac{GM}{R}$

The ratio of the escape velocity to the orbital velocity is

$\frac{v_e}{v_o}=\sqrt 2$
