Two coils have a mutual inductance 0.005 H. The current changes in the first coil according to equation \[I={{I}_{0}}\]is \[\sin \omega t\]where \[I=10A\]and \[\omega =100\pi \]radian/sec. The maximum value of e.m.f. in the second coil is:

A)  \[2\pi \]                              

B)         \[5\pi \]

C)  \[6\pi \]                              

D)         \[12\pi \]
