Question

The escape velocity of a body projected vertically upwards from the surface of the earth is v. If the body is projected in a direction making an angle  with the vertical, the escape velocity would be (a) v (b) v cos  (c) v sin  (d) v tan 

Answer 1

Escape velocity is Independent of the Angle of projection

For earth it has a constant value near about 11.2km/s

Answer 2
