STANDARD Physics Torricelli’s Law MCQ Question
Type: MCQ-numerical-Medium
A cylinder of height 20 m is completely filled with water. The velocity of efflux of water through a hole on the side wall of the cylinder near its bottom is (Take g = 10 m s⁻²)
A
10 m s⁻²
B
20 m s⁻²
C
5 m s⁻²
D
25.5 m s⁻²
Correct Answer
Option B
Detailed Explanation
According to Torricelli’s law, the velocity of efflux, v = √(2gh). Here, h = 20 m, g = 10 m s⁻². Therefore, v = √(2 × 10 × 20) = 20 m s⁻¹.
