A wire of length L, area of cross-section A is hanging from a fixed support. The length of the wire changes to L1 when mass M is suspended from its free end. The expression for Young’s modulus is
(1). \(\displaystyle \frac{Mg\left(L_1 - L\right)}{AL}\)
(2). \(\displaystyle \frac{MgL}{AL_1}\)
(3). \(\displaystyle \frac{MgL}{A\left(L_1-L\right)}\)
(4). \(\displaystyle \frac{MgL_1}{AL}\)
(1). \(\displaystyle \frac{Mg\left(L_1 - L\right)}{AL}\)
