Electromagnetic Induction question

2009 · Shift 2 · Q45

JEE AdvancedPhysicsElectromagnetic InductionMultiple correct+4 / −2
Two metallic rings A and B, identical in shape and size but having different resistivities ρA\rho_AρA​ and ρB\rho_BρB​, are kept on top of two identical solenoids as shown in the figure below. When current I is switched on in both the solenoids in identical manner, the rings A and B jump to heights hAh_AhA​ and hBh_BhB​, respectively, with hA>hBh_A \gt h_BhA​>hB​. The possible relation(s) between their resistivities and their masses mAm_AmA​ and mBm_BmB​ is (are) IIT-JEE 2009 Paper 2 Offline Physics - Electromagnetic Induction Question 5 English
