Answer 2

Answer:

Flux through the loop only changes when it enters and when it leaves the field. When it is fully inside the field or fully outside the field, the flux doesnt change.

When the flux changes, there is a current induced that opposes the cause according to Lenz's law. Therefore only when enetering and when leaving the field, the acceleration of the loop will be less than g. Other times, when it is fully inside the field or fully outside the field, the acceleration will be g.
