A body is released from the top of a tower ' H ' metre high. It takes t second to reach the ground. The height of the body t 2 second after release is

Options

  1. AH 2 metre from ground
  2. BH 4 metre from ground
  3. C3 H 4 metre from ground
  4. DH 6 metre from ground

Correct answer

C. 3 H 4 metre from ground

Step-by-step solution

Let the body be at x from the top after t 2 ~s . aligned x & = 1 2 ~g t ^2 4 = gt ^2 8 .... (i) H & = 1 2 gt ^2 .... (ii) aligned Eliminating t from (i) and (ii), we get 8 x g = 2 H g x = H 4 Height of the body from the ground = H - H 4 = 3 H 4 metres
