A body is imparted a velocity v from the surface of the earth. If v0 is orbital velocity and ve be the escape velocity then for
(A) v = v0, the body follows a circular track around the earth.
(B) v > v0 but < ve, the body follows elliptical path around the earth.
(C) v < v0, the body follows elliptical path and returns to surface of earth.
(D) v > ve, the body follows hyperbolic path and escapes the gravitational pull of the earth.
Answer & explanation
Correct answer: option 4
|
Velocity of Satellite |
Nature of Path |
|
v = v0 |
Circular path around the earth. |
|
v < v0 |
Elliptical path and body returns to earth. |
|
v > v0 but < ve |
Elliptical path around the earth and will not escape. |
|
v = ve |
Parabolic path and it escapes from the earth. |
|
v > ve |
Hyperbolic path and escapes from earth. |
