A rod of length l and negligible mass is suspended at its two ends by two wires of steel (wire A ) and aluminium (wire B) of equal length (shown in the figure)

The cross-sectional areas of wires A and B are 1.0 `mm^2` and 2.0 `mm^2`, respectively.
`(Y_(AL) = 70 xx 10^9 N m^-2` and `y _(steel) = 200 xx 10^9 N m^-2)`

A

Mass m should be suspended close to wire A to have equal stresses in both the wires.

B

Mass m should be suspended close to B to have equal stresses in both the wires

C

Mass m should be suspended at the middle of the wires to have equal stresses in both the wires

D

Mass m should be suspended close to wire A to have equal strain in both wires.
