Physics question help ?

Question

by rewriting each unit in terms of kg, m, s, and C, show that 1 N/C = 1 V/m

Answer 1

I am also "confused" as you are. You want to rewrite "kg", "m", "s" and "C" into

1 N/C = 1 V/m

My questions to you are --- what are "N" and "V" supposed to be? How are they related to "kg", "m" and "s"?

Answer 2

The reverse is easy. 1V=J/C=(Nm)/C So V/m=((Nm)/C)/(m)=(Nm)/(Cm)=N/C
