A lift is going up. The total mass of the lift and the passenger is 1500kg. The variation in the speed of the graph. The tension in the rope pulling the lift at `t=11^(th)` sec will be

A

17400N

B

14700N

C

12000N

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
C
At `11^(th)` second lift is moving upward with acceleration `a=(F)/(m)=(5)/(2)=2.5m//s^(2)`
Tension in rope, `T=m(g-a)` .
`1500(9.8-1.8)=12000N` .
