Two wires of same length and material but with radii 0.1 mm and 0.2mm are loaded with the same weight. Then

Two wires of the same material and same length have radii 1 mm and 2 mm respectively. Compare : their resistances,

Two wires of the same material (Young's modulus=Y) and same length L but radii R and 2R respectively are joined end to end and a weight w is suspended from the combination as shown in the figure. The elastic potential energy in the system is
