A) \[1.77\,\,V\]
B) \[17.7\,\,V\]
C) \[177\,\,V\]
D) \[0.177\,\,V\]
Correct Answer: B
Solution :
Induced\[emf\,\,e=\frac{-NA({{B}_{2}}-{{B}_{1}})\cos \theta }{\Delta t}\] \[=\frac{50\times \pi \times {{(3\times {{10}^{-2}})}^{2}}[0.35-0.10]\cos {{0}^{o}}}{2\times {{10}^{-3}}}\]\[\Rightarrow \]\[17.7\,\,V\]You need to login to perform this action.
