Question

A stream of water escapes from a hole 2 m above the base of a tank and strikes the ground at a horizontal distance of 6 m. The depth of the hole from the free surface of water is

  1. 4 m
  2. 4.5 m
  3. 9 m
  4. 6 m

The correct answer is: 4.5 m


    We know that R equals 2 square root of h left parenthesis H minus h right parenthesis end root
    Here R=6 m and H = h + 2
    rightwards double arrow 9 equals 2 h rightwards double arrow h equals 9 divided by 2
