  • Breaking stress of a wire depends on

    A
    the radius of the wire
    B
    the length of the wire
    C
    the shape of the cross-section
    D
    the nature of its material

  • This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement -I: The breaking stress of a wire is directly proportional ta its area of cross section. Statement - II: Greater the area of cross section of a wire, more load is required to break it. "Breaking stress" =Y xx "strain" , does not depend on area of cross-section, Breaking force prop area of cross section .

    A
    Statement - I is true, Statement - II is true, Statement - II is a correct explanation of Statement - I
    B
    Statement - I is true, Statement - II is true, Statement - II is not a correct explanation of Statement - I.
    C
    Statement - I is true, Statement -II is false.
    D
    Statement -I is false, Statement - II is true.
