Physics Question from JEE Main 2025 · 3 April, Shift 1

Consider a completely full cylindrical water tank of height $1.6 \, \text{m}$ and cross-sectional area $0.5 \, \text{m}^2$. It has a small hole in its side at a height $90 \, \text{cm}$ from the bottom. Assume, the cross-sectional area of the hole to be negligibly small as compared to that of the water tank. If a load $50 \, \text{kg}$ is applied at the top surface of the water in the tank then the velocity of the water coming out at the instant when the hole is opened is : ($g = 10 \, \text{m/s}^2$)
