Both values of acceleration in your question are the same. If that is correct then the answer would be 2.5 kg wt.

kropot72 · Answer

Let g = 9.81 m/s^2
Let m be the mass of the body
2.5 = 9.81m - (m * 1) = 8.81m
m = 2.5/8.81
Let x = reading at 2m/s^2
x = 9.81m - (m * 2) = 7.81m
Now you can substitute for m and find x.
