19. A body is fired with velocity V (greater than orbital velocity and less than escape velocity) at an angle 30 degree with the radius vector. If at highest point the speed of the body is v/4, then the maximum height (from the surface of earth) attained by the body is equal to (R=radius of earth) (A) v square/8g (B) 2R (C) (?2)RR |
