if n balls hit elastically and normally on a surface per unit time and all balls of mass m are moving with same velocity u, then force on surface is: (WHY CAN'T
The number of particle crossing per unit area perpendicular to Z axis per unit time is given by N= D(N2 N1)/(Z2 Z1), where N2 and N1 are the number of particle per
