A light rod of length 2 m is suspended from the ceiling horizontally by means of two vertical wires of equal length tied to its ends. One of the wires is made of steel and is of cross section 0.1 cm^2. The other wire is a brass of cross section 0.2 cm^2. A weight is suspended from a certain point of the rod such that equal stress are produced in both the wires. Which of the following are correct?

A uniform elastic rod of cross section area A natural length L and Young’s modulus Y is placed on a smooth horizontal surface. Now two horizontal forces (of magnitude F and 3F) directed along the length of rod and in opposite direction act at two of its ends as shown . After the rod has acquired steady state, the extension of the rod will be
