A particle of mass $8 \times 10^{-6} \mathrm{~g}$ is dropped from a certain height onto this sheet.

151744 Though the electron drift velocity is small and electron charge is very small, a conductor can carry an appreciably large current because:

If the density of the aluminum conductor is $\mathbf{2 . 7}$ $\mathrm{gm} / \mathrm{cc}$ considering aluminum gives 1 electrons per atom for conduction find the drift speed of the electrons if molecular weight of aluminum is $\mathbf{2 7} \mathbf{g m}$.
