Question $2$: Uniform soil whose $D_{10}$ is the No$.200$ opening

$(0\mathrm{.}074$ mm $)$ extends $3$ meters below the water table. The soil

above the water table has a unit weight of $18k\frac{N}{m^3}.$ Estimate:

a$)$ Capillary rise of the soil below the water table $($tip: round

to nearest meter$).$

b$)$ Effective stress at the top of capillary rise.

c$)$ Effective stress $3$ meters below the water table.
