Answer to Question #294647 in Physics for Wellen

Question

Two metallic plates are separated by a distance of 0.030 m at a potential difference of 60 V. Between the equipotential surfaces, there is a potential difference of 3.0 V. Find the spacing in this part of the field between the two metal plates.

Answer 1

Find the spacing:

$$E=V_1/d_1=V_2/d_2→d_2=V_2d_1/V_1=1.5\text{ mm}.$$
