How will the weight of an 20kg object change if it was in a lift that accelerates downwards at 4m.s-1

The weight as measured on a scale would be reduced by M*a,
from M*g to M*(g-a)
where a is the downward acceleration.
That is a reduction of 4/9.8 = 40.8%
If the scale is calibrated in kg, it would read 14.8 kg. They may want you to convert that to Newtons.

When an object is moving downwards its weight is 0kg.Because is in free-fall experiences the gravitational force.
