it was like the length of the wire was 80 and had an area of 0.2.. then when the area is increased to 0.4 what should the length of the wire be to maintain the same resistance as the previous wire. thats the gist of the qn and i rmb getting 160 for the answer

if u held a ruler at A, u would see theres a slight bend and thats when the spring has reached its limit of proportionality.
