T=m(g + a)=6000× (10 + 5)=90000 N

Q. An elevator weighing $6000 k g$ is pulled upwards by a cable with an acceleration of $5 m s^{- 2}$ . Taking $g$ to be $10 m s^{- 2}$ , the tension in the cable is

$6000 N$

$9000 N$

$60000 N$

$90000 N$

$T = m (g + a) = 6000 \times (10 + 5) = 90000 N$

Q. An elevator weighing 6000kg is pulled upwards by a cable with an acceleration of 5ms−2 . Taking g to be 10ms−2 , the tension in the cable is
