Q88 / 90 · JEE Main 2012 (19 May Online) · Physics

A steel wire can sustain $100 \mathrm{~kg}$ weight without breaking. If the wire is cut into two equal parts, each part can sustain a weight of

  • A
    $50 \mathrm{~kg}$
  • B
    $400 \mathrm{~kg}$
  • Correct answer
    C
    $100 \mathrm{~kg}$
  • D
    $200 \mathrm{~kg}$

Solution

Breaking force $\alpha$ area of cross section of wire Load hold by wire is independent of length of the wire.

Hence, the correct answer is option: 'C'.
