GATE Civil Engineering (CE) 2019 Shift 1 Solved Paper

For a given loading on a rectangular plain concrete beam with an overall depth of 500 $\mathit{m}\mathit{m}$, the compressive strain and tensile strain developed at the extreme fibers are of the same magnitude of $2.5\times {10}^{-4}$. The curvature in the beam cross-section (in ${\mathit{m}}^{-1}$, round off to 3 decimal places), is
