# What is the answer for this weird question?

Two identical blocks $$A$$ and $$B$$ of masses $$300$$ $$kg$$ and $$100$$ $$kg$$ respectively are placed on each other in two different possible ways on a mass measuring machine whose least count is $$10^{-30}$$ kg. In situation $$1$$, the block $$B$$ is placed on block $$A$$. And in situation $$2$$, the block $$A$$ is placed on block $$B$$. Let the reading of masses shown by machine in situation $$1$$ be $$m_{1}$$ and that in situation $$2$$ be $$m_{2}$$.

Find the value of $$\lfloor 10^{15} \times (m_{2} - m_{1}) \rfloor$$.

Details and Assumptions:

• The two masses are identical and the height of both blocks is $$1m$$ and base area is $$10000 m^{2}$$.

• Take acceleration due to gravity equal to $$10 m/s^{2}$$.

• The mass measuring machine is of high accuracy. It measures the mass of objects very accurately without any error up to the limit of its least count.

• $$\lfloor k \rfloor$$ is the greatest integer funtion. Example, $$\lfloor 2.3 \rfloor = 2$$.
