In a Youngβs double slit experiment, each of the two slits A and B, as shown in the figure, are oscillating about their fixed center and with a mean separation of 0.8 mm. The distance between the slits at time t is given by π = (0.8 + 0.04 sin ππ‘) mm, where π = 0.08 rad s β1 . The distance of the screen from the slits is 1 m and the wavelength of the light used to illuminate the slits is 6000 β«. The interference pattern on the screen changes with time, while the central bright fringe (zeroth fringe) remains fixed at point O.
Question: 1
The \(8^{th}\) bright fringe above the point O oscillates with time between two extreme positions. The separation between these two extreme positions, in micrometer (πm), is ______.

- A region in the form of an equilateral triangle (in x-y plane) of height L has a uniform magnetic field π΅β pointing in the +z-direction. A conducting loop PQR, in the form of an equilateral triangle of the same height πΏ, is placed in the x-y plane with its vertex P at x = 0 in the orientation shown in the figure. At π‘ = 0, the loop starts entering the region of the magnetic field with a uniform velocity π£ along the +x-direction. The plane of the loop and its orientation remain unchanged throughout its motion.
Which of the following graph best depicts the variation of the induced emf (E) in the loop as a function of the distance (π₯) starting from π₯ = 0? - Two beads, each with charge q and mass m, are on a horizontal, frictionless, non-conducting, circular hoop of radius R. One of the beads is glued to the hoop at some point, while the other one performs small oscillations about its equilibrium position along the hoop.
