Using either the Goldman or Parallel Conductance equations what would the Voltage of the membrane be at steady state if the membrane were twice as permeable to K$+$ as to Na$+($ i$.$e$.$ twice the g$)$ and the concentrations of the two ions in and out were the following: $[$K$+]$in$=100$ mM$,[$ K$+]$out$=10$ mM$,$ and $[$Na$+]$ in$=1$ mM and $[$Na$+$out$]=100$ mM$.$ Assume a temperature of $37$C$.$ A$)0$ mV B$)-122$ mV C$)-30\mathrm{.}5$ mV D$)-61$ mV
