Stretch 4 times mean length increased to 4L and Area reduced to one fourth 1/4 so putting values we'll get 16 times of original; there is a short cut for these types of MCQs Rnew=n^2 R where n is increase times

Jab wire streched ho to ye formula ae ga -->R=n2R ......aur jab compress ho to ye formula--->R=R/n4

uniformly means volume does no change as V is L INTO A. and resistance iss. resistivity into L\A A WILL BE A\4. YEAH 4 UPPR. 4L SATH. MULTIPLY HOGA AND ANSWER WILL BE 16
