Physics

# In a unit time, the number of particles crossing a unit area perpendicular to y-axis is given by $n = -A\cfrac{n_{2} - n_{1}}{y_{2} - y_{1}}$, where $n_{1}$ and $n_{2}$ are number of particles per unit volume for position $y =y_{1}$ and $y =y_{2}$ respectively. The dimensions of A is

$[M^{0}L^{2}T^{-1}]$
