# Show that 1 V/m = 1 N/C.

Proved that 1V/m=1N/C

See the step by step solution

## Step 1: Definition of electric potential

The Electric potential (V) is considered as the electric potential energy for an unit of charge.

Hence, the Sl unit of this parameter is (J/C)

## Step 2: Application of Joule’s Formula for energy

As per consideration It can be write as J/C in place of V;

As .

As, Joule is the product of force and displacement.

Hence it can be written as,

## Step 3: Prove that

Now it is proved that
