A person sitting inside an elevator performs a weighing experiment with an object of mass . Suppose that the variation of the height (in m) of the elevator, from the ground, with time (in s) is given by $ T = 40\pi \, \text{s} g = 10 \, \text{m/s}^2 $, the maximum variation of the object's weight (in N) as observed in the experiment is ____.
