Answer to Question #243288 in Physics for Pranav

Question

cylindrical vessel of radius of √2 m filled with water rotates with an angular speed of 100a vertical axis as shown in figure. If P_{B} - P_{A} = k * 10 ^ 7 Pa, then find the value of k.

Answer 1

$$P_{B} - P_{A} = k \cdot 10 ^ 7=0.5\rho \omega^2r^2\\ k \cdot 10 ^ 7=0.5(1000)(100)^22\\k=1$$
