Question

What is relationship between escape and orbital velocity.

Answer 1

Solution

If $v_e$ denotes escape velocity and $v_0$ Denote orbital velocity then relationship between escape and orbital velocity can be expressed as below

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

At the surface of earth

$v_e=\sqrt{2}v_0$ =$1.41v_o$
