A) \[48\,\mu V\]
B) \[36\text{ }\mu V\]
C) \[56\text{ }\mu V\]
D) \[28\text{ }\mu V\]
Correct Answer: C
Solution :
[c] Using faraday law Induced EMF \[=\left| -\frac{d\phi }{dt} \right|=\left| A\frac{dB}{dt} \right|\] \[\therefore \frac{dB}{dt}=\frac{1000-500}{5}\times {{10}^{-4}}={{10}^{-2}}T/\sec \] Area \[=\left( 16\times 42\times Area\text{ }of\text{ }triangle \right)c{{m}^{2}}\] \[=\left( 64-2\times \frac{1}{2}\times 2\times 4 \right)c{{m}^{2}}\] \[=56\times 104{{m}^{2}}\] \[\therefore {{\varepsilon }_{induced}}=56\times {{10}^{6}}\text{ }V=56\text{ }\mu V\]You need to login to perform this action.
