Question

An elevator weighing 6000 kg is pulled upward by a cable with an acceleration of $5ms^{- 2}$. Taking g to be $10ms^{- 2}$, then the tension in the cable is

• A. 6000 N
• B. 9000 N
• C. 60000 N
• D. 90000 N

Answer 1

Answer: (D)

90000 N

Answer 2

$T = m(g + a)$ $T = 6000(10 + 5)$ $T = 90,000N$
