Pls answer tbis question it is PYQ and experts pls recheck ur answer b4 posting the answer the answer of this question according to me should be B but the answerr is given C pls explain
Dear Student
Area A of wire is directly proportional to diameter square
So extension is large for wire for which ratio l/D2 is greater.
As in case ,b l/D2 = 3.3 x 103 cm -1
As in case c, l/D2 = 20 x 103 cm -1
Hence extension is maximum in c case.
