Q. A particle of mass

m

is projected with a velocity

v = k v_{e} (k < 1)

from the surface of the earth.

(v_{e} =

escape velocity

)

. The maximum height above the surface reached by the particle is -

Q. Assertion :If a particle projected horizontally just above the surface of the earth with a speed greater than escape speed, then it will escape from gravitational influence of the earth. Assume that particle has a clear path. Reason: Escape velocity is independent of its direction.
