Figure shows a conducting rod of negligible resistance that can slide on smooth \( U \)-shaped rail made of wire of resistance \( 1 \Omega / \mathrm{m} \). Position of the conducting rod at \( t=0 \) is shown. A time dependent magnetic field \( B=2 t \) tesla is switched on at \( t=0 \).
\( \mathrm{P} \)
W
The current in the loop at \( t=0 \) due to induced emf is
(a) \( 0.16 \mathrm{~A} \), clockwise
(b) \( 0.08 \mathrm{~A} \), clockwise
(c) \( 0.16 \mathrm{~A} \), anti-clockwise
