A rigid bar of mass is supported symmetrically by three wires each of length . Those at each end are of copper and the middle one is of iron. The ratio of their diameters, if each is to have the same tension, is equal to
View answer and explanation
Correct option: B
Option B () is correct because the ratio of diameters is related to the square root of the ratio of Young's moduli to maintain the same tension in each wire.
