Un the figure below, two rectanglular loops move towards a region of uniform magnetic field. For the loops, the side labeled "a" is four times the length of the side labeled "b". If both loops have the same induced emf, which loop has the lesser speed? Explain your reasoning. If both loops have the same induced speed, explain why. The image shows a schematic representation of a rectangular object and a pattern of circular objects:1. **Rectangular Object:** - Two rectangles are depicted: one standing upright and labeled with dimensions `a` (height) and `b` (width), and the other lying horizontally, maintaining the same dimensions. - An arrow labeled `v` points towards the right, indicating possible movement or orientation change from vertical to horizontal alignment.2. **Pattern of Circles:** - On the right side, there is a grid pattern consisting of circles arranged in rows and columns. - Each circle has a smaller concentric circle inside, resembling a ring. - The entire pattern is labeled with the letter `B`.This diagram may illustrate a concept related to structural design, material arrangement, or a physics principle such as motion, symmetry, or material packing. The specific context would determine its relevance and application.

The expression for the motional emf is as follows: ε=Blv 1 Here, l is the length of the loop entering or leaving the field. When whole loop has entered the field, no further change in flux hence then no emf will be induced. emf is induced when entering or leaving the field region.Since the induced emf by both the loops are same. Compare the emf of two loops to solve for the ratio of the velocities. Bbv1=Bav2Bbv1=B4bv2v1v2=4 2 Here, v1 is the speed of loop with length b, v2 is the speed of the loop with length a. The loop with length a is having lesser speed than loop with length b.
