MCQ
An elevator weighing $6000 kg$ is pulled upward by a cable with an acceleration of $5 ms ^{-2}$. Taking $g$ to be $10 ms ^{-2}$, then the tension in the cable is
  • A
    $6000 N$
  • B
    $9000N$
  • C
    $60000 N$
  • ✓
    $90000 N$
✓

Answer

Correct option: D.
$90000 N$
(d) $T=m(g+a)=6000(10+5)=90000 \mathrm{~N}$
