The tension force pulling the elevator up is equal to 1,932 N.
First, to calculate the value of the tension responsible for the acceleration of the system, it is necessary to understand how the forces are distributed in the system, so that:
[tex]T - m\times g = m \times a[/tex]
The resultant force is equal to the subtraction of the tension applied to the elevator and the weight of the elevator.
That said, we can apply the given values, having:
[tex]T - 300\times 2.940 = 300 \times 3.5[/tex]
[tex]T = 1,932 N[/tex]
So, the tension force pulling the elevator up is equal to 1,932 N.
