Question

A tank, placed on the ground, is filled with water up to a height ℎ. A small hole is made at a height ℎ1 such that ℎ1 < ℎ. The water jet emerging from the hole strikes

the ground at a horizontal distance D, as shown schematically in the figure. Which of the following statements is correct? (g is the acceleration due to gravity)

• A. Velocity at ℎ1 is $\sqrt{2𝑔ℎ_1}$
• B. 𝐷 = 2(ℎ − ℎ1)
• C. D will be maximum when ℎ1 = $\frac{2}{3}$ ℎ
• D. The maximum value of D is h

Answer 1

Answer: (D)

The maximum value of D is h

Answer 2

The correct option is (D): The maximum value of D is h
