Short Answer

In a Millikan oil-drop experiment (Module 22-6), a uniform electric field of $1 .92 \times 10^{5} N / C$ is maintained in the region between two plates separated by $1.50 cm$ . Find the potential difference between the plates.

The potential difference between the plates is, $2.9 kV$ .

Step 1: Identification of the given data

The uniform electric field is, $E = 1.92 \times 10^{5} N / C$ .

The separation between the two plates is, $R = 0.015 m$

Step 2: Understanding the concept

According to the definition, the electric potential gradient ‘ $E$ ’ is given as:

role="math" localid="1662732704306" $E = - \frac{\partial ν}{\partial R}$

$\begin{matrix} \int \partial V = E \times \int \partial R \\ V = ER \end{matrix}$

Step 3: Calculate the potential difference between the plates

The potential difference between the plates is expressed is,

$V = ER$

Substitute all the value in the above equation.

$\begin{matrix} V = 1.92 \times 10^{5} N / C \times 0.015 m \\ = 2.88 \times 10^{3} V \\ = 2.9 kV \end{matrix}$

Hence the potential difference between the plates is, $2.9 kV$ .
