Physics Question from JEE Main 2023 · 10 April, Shift 1

A closed circular tube of average radius $15 \, \text{cm}$, whose inner walls are rough, is kept in a vertical plane. A block of mass $1 \, \text{kg}$ is introduced at the top of the tube with a speed of $22 \, \text{m/s}$. After completing five oscillations, the block stops at the bottom of the tube. The work done by the tube on the block is:
