Question

Two large parallel metal plates carry opposite charges. They are separated by 0.20 m and the p.d. between them is 500 V. What is the magnitude of electric field, if it is uniform, in the region between them.​

Answer 1

Hi there!

We can use the following relationship between the Potential Difference and the Electric field:

`V = E d`

V = Potential Difference (500V)
E = Electric Field (V/m)
d = separation between plates (0.2 m)

We can rearrange the equation to solve for the electric field:

`E = (V)/(d)\\\\`

Plug in the given values.

`E = (500)/(0.2) = \boxed{2500 (V)/(m)}`
