The compaction curve for a soil sample is given below. What will be the void ratio $($e$)$ at point $B$ if the void ratio at point $A$ is $0\mathrm{.}8?$

vioisture content $70$

Hint: See the below equation for the dry unit weight in relation to the void ratio:

$\frac{G.{}_u}{1+e}$

It is noted that points A and $B$ have the same value of dry unit weight. Gs and water unit weight are constant values.

a$.0\mathrm{.}65$

b$.0\mathrm{.}5$

c$.0\mathrm{.}75$

d$.0\mathrm{.}8$
