A satellite is orbiting close to the earth and has a kinetic energy ( K ). The minimum extra kinetic energy required by it to just overcome the gravitation pull of the earth is

Step-by-step solution

(B) We know ( v_ e = 2 v₀ ) When satellite is in orbit ( K= 1 2 m v₀ ² ) For satellite to escape its velocity should be ( v_ e ) ( K E ) To escape, ( K_ e = 1 2 m v_ e ²= 1 2 m ( 2 v₀ )²=2 K ) ( ) Extra ( K . E ). required ( =2 K-K=K )
