A body is projected vertically upwards with a velocity from the top of a tower. Time taken by it to reach the ground is times the time taken by it to reach the highest point in its path. Height of the tower is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Let us suppose. h is the height of the tower and it attains maximum height up to H from ground, so Time to reach the maximum height, t=ug if t2 is the time taken by the ball to hit the ground, -H=ut2-12gt22 t2=nt -H=unt-12gnt2⇒-H=unug-12gn×ug2⇒H=nu2n-22g
