A cylinder of height 1 ~m is filled with water. If a small orifice is made at a height of 0.25 ~m from the ground, the horizontal range of water stream will be

Options

  1. A46.5 ~cm
  2. B56.6 ~cm
  3. C76.6 ~cm
  4. D86.6 ~cm

Correct answer

D. 86.6 ~cm

Step-by-step solution

v= 2 g h = 2 10 0.75 = 15 ~m ~s ⁻¹ Horizontal range, aligned & R= 2 h g 15 = 2 0.25 15 10 = 15 20 = 3 4 & = 1.732 2 =0.866 ~m =86.6 ~cm aligned
