Answer:
41.4% is the correct answer
how
Let A satellite is moving around the earth with velocity=v
We know that the maximum orbital velocity of a satellite orbiting near the earth surface is,
v=(gR)
2
1
=v0
And the escape velocity V
e
=v0×(2)
2
1
=1.414×v0
So,
Increase in the velocity = V
e
–v0=(1.414−1.000)v0=0.414v0
Thus the Percentage increase = 41.4%
