a. the tension i the string is found out for the different conditions from the free diagram as shown below

`T-(W+0.05xx1.2`
` =0.05(9.8+1.2)`
`= 0.55N`
b. Now
`T+0.05xx1.2-0.05xx9.8=0`
` rarr T=0.05xx9.8=0.05xx1.2`
`= 0.05(9.8-1.2)`
`=0.05xx8.6`
`=0.43N`
c. When the elevator makes uniform motion,
`T-W=0`
`rarr T=W=0.05xx9.8=0.49N`
d. `T+ 0.05xx1.2-w=0`
`rarr T=w-0.05xx1.2`
`=0.05(9.8-1.2)=0.43N`
e.`T-(W+0.05xx1.2)=0`
`rarr T= W+0.05xx1.2`
` rarr 0.05(9.8+1.2)=0.55N`.
f. When the elevator goes down with uniform velocity acceleration =0.
`:. T-W=0`
`rarr T=W= 0.05xx9.8`
`=0.49N`.
