None of these

1.	An inductor \[20\times {{10}^{-3}}\] Henry, a capacitor \[100\,\mu F\]and a resistor \[50\,\Omega \] are connected in series across a source of EMF V=10 sin 314t. If resistance is removed from the circuit and the value of inductance is doubled, then the variation of current with time in the new circuit is -
A.	\[0.52\text{ }cos\text{ }314t\]
B.	\[0.52\text{ }sin\text{ }314t\]
C.	\[0.52\,\sin \,(314t+\pi /3)\]
D.	None of these
Answer» B. \[0.52\text{ }sin\text{ }314t\]
