We have, mass(m) deposited is
{tex}m = Z \times I \times t{/tex}
{tex}m = \frac{{108}}{{96500}} \times 0.5 \times 2 \times 60 \times 60{/tex}
{tex} = \frac{{108 \times 5}}{{965 \times 10}} \times 2 \times 6 \times 6{/tex}= 4.03 g
{tex}4.03g = V \times d{/tex}
{tex}4.03g = V \times 10.5gc{m^{ - 3}}{/tex}
V = Area {tex} \times {/tex} Thickness
{tex}V = \frac{{4.03}}{{10.5}}{/tex}
{tex}\frac{{4.03}}{{10.5}} = 900c{m^2} \times {/tex} thickness
Thickness {tex} = \frac{{0.338c{m^3}}}{{900c{m^2}}}{/tex}
{tex} = 4.26 \times {10^{ - 4}}cm{/tex}
