A region in the form of an equilateral triangle (in plane) of height has a uniform magnetic field pointing in the -direction. A conducting loop , in the form of an equilateral triangle of the same height , is placed in the plane with its vertex at in the orientation shown in the figure. At , the loop starts entering the region of the magnetic field with a uniform velocity along the -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 in the loop as a function of the distance starting from ?
