In anexperimental a nerve cell was isolated to determine it's RMP .Electrophysiologic measurement revealed.
Equilibrum potential of K -100mV
Equil potential of Na +50mV
Conductance k 8
Conduc Na 2
Using these values resing membrane potential is calculated to be
a)-50mV
b)-70mV
c)50mV
d)70mV
e)100mV

Its B -70 mV. I am sure...

RMP=(50*2-100*8)/(2+8)=-70mv
