6. In the adjacent circuit, initially capacitors \( A \) and \( B \) are charged by voltage \( 2 E \) and \( E \) respectively. Initial current through the inductor is zero and switch ' \( S \) ' is closed at \( t=0 \). The maximum current through the inductor is
Capacitor- \( A \)
(1) \( E \sqrt{\frac{C}{L}} \)
(2) \( E \sqrt{\frac{C}{2 L}} \)
(3) \( E \sqrt{\frac{2 C}{L}} \)
(4) \( E \sqrt{\frac{C}{3 L}} \)
