A) 0.000558 per \[{}^\circ C\]
B) 0.00057 per \[{}^\circ C\]
C) 0.00027 per \[{}^\circ C\]
D) 0.00066 per \[{}^\circ C\]
Correct Answer: B
Solution :
Volume coefficient of expansion =\[7\times {{10}^{-5}}wb/{{m}^{2}}\] linear coefficient of expansion \[I={{I}_{0}}{{e}^{-d/\lambda }}\] \[I={{I}_{0}}{{e}^{d\lambda }}\] Given, volume expansion of glycerine is \[I={{I}_{0}}(1-{{e}^{-d\lambda }})\] Apparent volume coefficient of expansion \[1.25\times {{10}^{18}}\] \[3.125\times {{10}^{13}}\]
