A) 0.1 sec
B) 0.01 sec
C) 1 sec
D) 20 sec
Correct Answer: A
Solution :
\[e=-\frac{N({{B}_{2}}-{{B}_{1}})A\,\cos \theta }{\Delta t}\] \[\Rightarrow \]\[0.1=\frac{-50\times (0-2\times {{10}^{-2}})\times 100\times {{10}^{-4}}\times \cos {{0}^{o}}}{t}\] \[\Rightarrow \]\[t=0.1\,\sec .\]You need to login to perform this action.
