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 ............ $N$
- A$6000$
- B$9000$
- C$60000$
- ✓$90000$
✓
Answer
Correct option: D.
$90000$
d
$T = mg + ma$
$T = mg + ma$
$= 6000 (10 + 5) = 90,000\, N$
