Question

How many times is escape velocity (V.), of orbital velocity (V.) for a satellite revolving near earth -
(1) V2 times (2) 2 times
(3) 3 times
(4) 4 times​

Answer 1

Answer:

aacording to my knowledge this is the correct answer !

The ratio between the orbital velocity and escape velocity in Newtonian Physics is √2. That means Escape velocity is √2 times the orbital speed for a satellite revolving near earth
