A conducting loop in the shape of a right angled isosceles triangle of height 10 cm is kept such that the 90°vertex is very close to an infinitely long conducting wire (see the figure). The wire is electrically insulated fromthe loop. The hypotenuse of the triangle is parallel to the wire. The current in the triangular loop is incounterclockwise direction and increased at a constant rate of 10 As–1. Which of the following statement(s)is(are) true?(A) There is a repulsive force between the wire and the loop(B) If the loop is rotated at a constant angular speed about the wire, an additional emf of munot/pi volt is inducedin the wire(C) The magnitude of induced emf in the wire is munot/pi volt(D) The induced current in the wire is in opposite direction to the current along the hypotenuse |
