Show that the unit Vm-1 (volt per meter) is equivalent to NC-1(newtons per coulomb)?

Answer 1

Favorite Answer

F(Newtons) = kQ*Q / r^2 ........coulombs law

=> N/C=F(newtons)/Q = kQ / r^2 .......1

F/Q= E(Electric field) = kQ / r^2

=>V(Electric potential) = E*r ............2

From 1 and 2

F/Q = V/r = (volt /meter) = (newtons/coulombs)

Hence proved (volt per meter) is equivalent to (newtons per coulomb)

Answer 4

That's an interesting question!

Answer 5

1 volt = joule/coulomb

1 Joule = N*m

V/m =J/m*C = N*m/m*C = N/C
