A metal metre scale that is accurate up to 0.5 mm is made at a temperature of 25^{\circ} {\C}. The range of temperatures within which it can be used is (Coefficient of linear expansion of the metal =10^{-5} \/{ }^{\circ} {\C} )

Correct Answer is : −25∘C to +75∘C

+25^{\circ} {\C} \text{ to }+75^{\circ} {\C}

+25^{\circ} {\C} \text{ to }+50^{\circ} {\C}

-25^{\circ} {\C} \text{ to }+75^{\circ} {\C}

0^{\circ} {\C} \text{ to }+50^{\circ} {\C}
