Question:
The velocity of efflux of a liquid through an orifice in the bottom of the tank does not depend upon
The velocity of efflux of a liquid through an orifice in the bottom of the tank does not depend upon
Show Hint
The velocity of efflux from an orifice depends only on the height of the liquid and gravitational acceleration, not on the size of the orifice.
Updated On: Jan 12, 2026
- size of orifice
- height of liquid
- acceleration due to gravity
- density of liquid

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Use Torricelli's law.
The velocity of efflux of a liquid from an orifice is given by: \[ v = \sqrt{2gh} \] where \( h \) is the height of the liquid and \( g \) is the acceleration due to gravity.
Step 2: Conclusion.
The velocity of efflux does not depend on the size of the orifice, only on the height of the liquid and the acceleration due to gravity.
Final Answer: \[ \boxed{\text{size of orifice}} \]

- The Hamiltonian for a one-dimensional system with mass \( m \), position \( q \), and momentum \( p \) is: \[ H(p, q) = \frac{p^2}{2m} + q^2 A(q) \] where \( A(q) \) is a real function of \( q \). If \[ m \frac{d^2 q}{dt^2} = -5q A(q), \] then \[ \frac{d A(q)}{d q} = n \frac{A(q)}{q}. \] The value of \( n \) (in integer) is:

Choose the correct answer from the options given below:
- Two forces acting at a point of a body are equilibrium if and only if they
(A) are equal in magnitude
(B) have same direction
(C) have opposite direction
(D) act along the same straight line
(E) are not equal in magnitude but have same direction
Choose the correct answer from the options given below: - If three forces of magnitudes 8 newtons, 5 newtons and 4 newtons acting a point are in equilibrium, then the angle between the two smaller forces is
