When the oil from a circular cylinder leaked, the formula for the speed of the leak is V = kh^2, where h was the height of the remaining oil and k was constant. If the height of the cylinder is 4, the speed of the leak is Vâ€™, When the height of the oil remaining is 16, what was the speed of the leak, in terms of Vâ€™?	Choose the correct answer
A) 2Vâ€™  B) 4Vâ€™  C) Vâ€™/2  D) Vâ€™/4  E) 16Vâ€™
When h=4 v=V'   So V' = k.16   Hence k = V'/16   Now when h=16   v=(V'/16).16^2   v=V'.16   v=16V'   Ans : 16Vâ€™
