Heat and Thermodynamics question

2023 · 24 Jan · Shift 1 · Q66

JEE MainPhysicsHeat and ThermodynamicsNumerical+4 / −1
A hole is drilled in a metal sheet. At 27∘C\mathrm{27^\circ C}27∘C, the diameter of hole is 5 cm. When the sheet is heated to 177∘C\mathrm{177^\circ C}177∘C, the change in the diameter of hole is d×10−3\mathrm{d\times10^{-3}}d×10−3 cm. The value of d will be ‾\underline{\hspace{2cm}}​ if coefficient of linear expansion of the metal is 1.6×10−5/∘1.6\times10^{-5}/^\circ1.6×10−5/∘ C.
