Question How much force is required to produce an increase of \( 0.2 \% \) in the length of a brass wire of diameter \( 0.6 \mathrm{~mm} \)
(Young's modulus for brass \( =0.9 \times 10^{11} \mathrm{~N} / \mathrm{m}^{2 \text { ) }} \)
(A) Nearly \( 17 \mathrm{~N} \)
(B) Nearly \( 34 \mathrm{~N} \)
(C) Nearly \( 51 \mathrm{~N} \)
(D) Nearly \( 68 \mathrm{~N} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
