A) \[300\,\pi \]
B) \[3000\,\pi \]
C) \[3\,\pi \]
D) \[30\,\pi \]
Correct Answer: D
Solution :
Peak value of induced emf in a rectangular coil is \[e=n\,BA\,\,\omega \,\sin \theta \] \[=300\times 4\times {{10}^{-2}}\times (25\times 10\times {{10}^{-4}})\] \[\times (2\pi \times 50)\times \sin \,{{90}^{o}}\] \[=30\,\,\pi \]voltYou need to login to perform this action.
