Wires \( A \) and \( B \) are connected with mass \( m \) as shown in figure. Wires are of same material and have radii \( r_{A} \) and \( -r_{B} \). End of \( B \) is pulled with a force of \( m g / 3 \). With reference to the above situation, which of the following statement is correct?
(a) \( A \) breaks before \( B \) when \( r_{A}=r_{B} \)
(b) \( A \) breaks after \( B \) when \( r_{A}2 r_{B} \)
(c) Neither \( A \) nor \( B \) will break if \( r_{A}=2 r_{B} \)
(d) None of the above
\( \mathrm{W} \)
