A projectile is projected with velocity
A projectile is projected with velocity kve in vertically upward direction from the ground into the space. (ve is escape velocity and k<1) . If air resistance is considered to be negligible then the maximum height from the centre of earth to which it can go, will be : (R = radius of earth)
(a) R/k2 +1 (b) R/k2 -1
(c) (b) R/1 – k2 (d) R/k + 1
Answer: c
