$($c$)$ For the same soil prepared under the same conditions and same initial void ratio as in Q$3($b$),$ the critical state parameters $,$ and N are found to be $0\mathrm{.}10,2\mathrm{.}05$ and $2\mathrm{.}17,$ respectively. Another CU triaxial test is conducted with effective confining pressure $(3)$ of $300$ kPa.
