Physics Question from JEE Main 2025 · 4 April, Shift 2

A cylindrical rod of length $1 \, \text{m}$ and radius $4 \, \text{cm}$ is mounted vertically. It is subjected to a shear force of $10^5 \, \text{N}$ at the top. Considering infinitesimally small displacement in the upper edge, the angular displacement $\theta$ of the rod axis from its original position would be: (shear moduli $G = 10^{10} \, \text{N/m}^2$)
