❒ The number of particles crossing per unit area perpendicular to z axis per unit time is given by , N = -D ( N₂ - N₁) / ( Z₂ - Z₁ ) , where N₁ and N₂ are the number of particles per unit Volume at Z₁ and Z₂ respectively . What is the dimensional formula of D ?
Need to FinD :-
- The dimensional formula of D .
And N₁ and N₂ ate the number of particles per unit Volume at Z₁ and Z₂ respectively .
Hence the Dimensional Formula is [M⁰L²T-¹] .
