140938 Two wires of the same material and length but diameters in the ratio $1: 2$ are stretched by the same force. The elastic potential energy per unit volume for the wires, when stretched by the same force will be in the ratio.

140939 When a force $F_{1}$ is applied on a metallic wire, the length of the wire is $L_{1}$. If a force $F_{2}$ is applied on the same wire, the length of the wire is $L_{2}$. The original length of the wire $L$ is
