Two inductors of self inductances `L_(1)` and `L_(2)` of reistances `R_(1)` and `R_(2)` (not shown in the diagram) respectively, are connected in the circuit as shown in the figure. At the instant `t=0`, key `K` is closed, obtain the condition for which the galvanometer will show zero deflection at all times after the key is closed.

A conducting rod is bent as a parabola y=Kx^(2), where K is a constant and it is placed in a unifrom magnetic field of induction B. At t=0 a conductor of resistance per unit length lambda starts sliding up on the parabola with a constant acceleration a and the parabolic frame starts rotating with constant angular frequency omega about the axis of symmetry, as shown in the figure. Find the instantaneous current induced in the rod, when the frame turns through pi//4rad.
