A satellite revolving around a planet has orbital velocity 10 ~km / s . The additional velocity required for the satellite to escape from the gravitational field of the planet is

Options

  1. A14.14 km/s
  2. B11.2 km/s
  3. C4.14 km/s
  4. D41.4 km/s

Correct answer

C. 4.14 km/s

Step-by-step solution

The relation between two velocities is given by the relation aligned & v_ e =( 2 -1) v₀ & =(1.414-1) v ₀ & =0.414 10=4.14 ~km / s aligned
