Question

A Geostationary satellite is revolving around the earth. To make it escape from gravitational field of earth, its velocity must be increased –

• A. 100 %
• B. 41.4%
• C. 50%
• D. 59.6%

Answer 1

Answer: (B)

41.4%

Answer 2

v_e = $\sqrt{2}v_{0}$= 1.414 v₀ % increase in orbital velocity = $\frac{v_{0}–v_{0}}{v_{0}} \times 100$= 41.4 %
