We have, Length of copper wire rarr L=1.10m Change in length of copper wire rarr Delta L Diameter of copper wire rarr d=1.024mm=1.024 xx10^(-3)m Weight of ball rarr W=100N Change in the wight of the ball rarr Delta W=500N Young's Modulus of copperrarr E=11 xx10^(10)Pa Cross sectional area of the copper wire is calculated as: A=pi((d)/(2))^(2) :.A=pi((1.024 xx10^(-3))/(2))^(2) :.A=8.2355 xx10^(-7)m^(2)   Young modulus is given as a ratio ...
