Question

A wire can sustain the weight of $20kg$ before breaking. If the wire is cut into two equal parts, each part can sustain a weight of

• A. $10kg$
• B. $20kg$
• C. $40kg$
• D. $80kg$

Answer 1

The correct option is B $20kg$

$The$ $breaking$ $stress$ $in$ $each$ $part$ $of$ $the$ $wire$ $will$ $be$ $the$ $same$ $as$ $the$ $original$ $because$ $of$ $the$ $same$ $material.$ $Since$ $the$ $area$ $remains$ $the$ $same,$ $each$ $part$ $can$ $sustain$ $a$ $weight$ $of$ $20$ $kg.$
