A steel wire of diam...d , area A and length 2l is clamped firmly at two points a and b which are 2l apart and in the same plane.A body of mass m is hung from the middle point of wire such that the middle point sags by x lower from original position. If Young's modulus is then m is given by
1. 1/2 * k x2/l2
2.1/2 * k l2/x2
3.k *x2/l2
4.k*l2/x2
where k = YA/g
youngs mod-Y, gravity -g , area -A
