Question

A satellite orbiting the earth with speed v0. To make the satellite escape, what should be the minimum percentage increase in its velocity?

(a) 41.5%

(b) 44.1%

(c) 41.4%

(d) 40%

I have been asked this question in a job interview.

The question is from Gravitational and Gravity topic in division Gravitation of Engineering Physics I

Answer 1

Correct choice is (c) 41.4%

For explanation: Required percentage increase in velocity = (ve-v0)/v0 ×100

(√2-1)×100=41.4%.
