Given data, WE = 5000N, a = 3m/sec^{2}, WO = 700N,

Let R = Reaction offered by floor on operator. This is also equal to the reading of scale.

T = total tension in the cable

Net upward force on operator

= Reaction offered by floor on operator – Weight of operator

= R – 700

But, Net force = ma

R – 700 = (700/9.81)X 3

**R = 914.28N**

Now for finding the total tension in the cable, Total weight of elevator is considered.

Net upward force on elevator and operator

= Total tension in the cable – Total weight of elevator and operator

= T – 5700

But net force = mass X acceleration

T – 5700 = (5700/9.81) X 3

**T = 7445N**
