A metal bar AB can slide on two parallel thick metallic rails separated by a distance l. A resistance R and an inductance L are connected to the rails as shown in the figure. A long straight wire carrying a constant current I_(0) is placed in the plane of the rails and perpendicular to them as shown. The bar AB is held at rest at a distance x_(0) from the long wire. At t=0, it is made to slide on the rails away from wire. Answer the following questions.

A double slit interference pattern is produced on a screen, as shown in the figure, using momochromatic light of wavelength 500 nm. Point P is the location of the central bright fringe, that is produced when light waves arrive in phase without any path difference. A choice of the three strips A, B and C of transparent materials with different thickness and refractive indices is available, as shown in the table. These are placed over one or both of the slits, singularly or in conjunction causing the interference pattern to be shifted across the screen from the original pattern. In the Column - I, how the strips have been placed, is mentioned whereas in the Column-II, order of the fringe at point P on the screen that will be produced due to the placement of the strip(s), is shown. Correctly match both the column.

An ammeter with resistance R_A is connected in series with a resistor R, a battery of emf c and internal resistance r . The current measured by the ammeter is I_A . Find the current through the circuit if the ammeter is removed so that the battery and the resistor form a complete circuit. Express your answer in terms of I_A, r, R_A and R . Show that more "ideal" the ammeter, the smaller the difference between this current and the current I_A . ltbr.
