Chapter 17, Problem 5P

To determine

The electric field between two parallel plates.

Answer to Problem 5P

The electric field between two plates is $\text{37}\text{.9}\times {\text{10}}^3\text{V/m}$ .

Explanation of Solution

Given info:

The distance between the plates is $d=5.8\text{mm}$ .

The potential difference between the plates is $\Delta V=220\text{V}$ .

Formula used:

The applied electric field is,

  $E=\frac{\Delta V}{d}$

Calculation:

Substituting the given values, we get

  $\begin{array}{c}E=\frac{220}{5.8\times {10}^{-3}}\text{V/m}\\ =\text{37}\text{.9}\times {\text{10}}^3\text{V/m}\end{array}$

Conclusion:

Thus, the electric field between two plates is $\text{37}\text{.9}\times {\text{10}}^3\text{V/m}$ .
