A cylindrical copper rod has length L and resistance R. If it is melted and formed into another rod of length 2L, the resistance will be

A metal rod of length 'L' and mass 'm' is piovted at one end. A thin disk of mass 'M' and radius 'R' (lt L) . Is attached at its centre to the free end of the rod. Consider two ways the disc is attached: (case A ). The disc is not free to rotate about its centre and (case B ) the disc is free to rotate about its center. The rod-disc sustem perform SHM in vertical plane after being released from the same displaced potion. Which of the following statement(s) is (are) true?
