A) 1.77 V
B) 17.7 V
C) 177 V
D) 0.177 V
Correct Answer: B
Solution :
Induced emf \[e=\frac{-NA({{B}_{2}}-{{B}_{1}})cos\theta }{\Delta t}\] \[=\frac{50\times \pi \times {{(30\times {{10}^{-2}})}^{2}}[0.35-0.10]cos{{0}^{o}}}{2\times {{10}^{-3}}}\] \[\Rightarrow \] \[=17.7\,V\]You need to login to perform this action.
