Two wires have identical lengths and areas of cross-section are suspended by mass `M`. Their Young's modulus are in the ratio `2:5`.

Two wires of equal length and cross-section area suspended as shown in figure. Their Young's modulus are Y_(1) and Y_(2) respectively. The equavalent Young's modulus will be

Two wires of equal length and cross-section area suspended as shown in figure. Their Young's modulus are Y_(1) and Y_(2) respectively. The equavalent Young's modulus will be

Two springs of equal lengths and equal cross sectional area are made of materials whose young's moduli are in the ratio of 3 : 2. They are suspended and loaded with the same mass. When stretched and released, they will oscillate with time period in the ratio of

An iron wire an copper wire having same length and cross-section are suspended form same roof Young's modulus of copper is 1//3rd that of iron. Then the ratio of the weighs to be added at their ends so that their ends are at the same level is

Two wires of equal length and equal cross sectional area are suspended as shown in the figure their young modulii are y_(1) and y_(2) respectively the equaivalent young 's modulus is
