NEET Physics (general) MCQ Question

Type: MCQ-numerical-Medium-Class 11

Using Bernoulli's equation, what is the speed of efflux from a hole at the side of a container filled with water to a height of 5 meters, assuming the container is open to the atmosphere?

A

9.9 m/s

B

7.5 m/s

C

5.5 m/s

D

11.2 m/s

Correct Answer

Option A

Detailed Explanation

The speed of efflux is calculated using Torricelli’s law derived from Bernoulli’s equation, v = √(2gh). For h = 5 m, v = √(2 * 9.8 m/s² * 5 m) = 9.9 m/s.
