7 A uniform magnetic field B exists in circular region of radius R as shown which is decreasing with time at a constant rate There is a concentric wooden ring which have uniformly distributed charge Q and radius 2R and another concentric uncharged copper ring of radius 3R then select INCORRECT alternative Assume rings are placed on frictionless surface 3R R 2R 1 There is no induced current in wooden ring 2 Induced electric field in wooden ring is more in magnitude than copper ring 3 Induced electric field in copper ring is more in magnitude than wooden ring
