Question

A satellite is revolving around earth in a circular orbit. At some instant the speed of the satellite is increased √2 times its orbital speed keeping its direction unchanged. Then, the new path of the satellite is : 

(A) circular 

(B) straight line 

(C) elliptical 

(D) parabolic

Answer 1

Correct option (D) parabolic

Explanation:

The orbital velocity,

Its velocity is increased by √2 times, new velocity

 = escape velocity

The path is parabolic in case of escape velocity.
