Question

A test charge $q_0$ is released from rest at a distance $r$ from a source charge $q$. What will be the maximum value of the kinetic energy that may be acquired by the test charge ?

• A. $\frac{1}{4\,\pi\,\varepsilon_0}\frac {qq_0}{r}$
• B. $\frac{1}{4\,\pi\,\varepsilon_0}\frac {q^2}{r}$
• C. $\frac{1}{4\,\pi\,\varepsilon_0}\frac {q_0^2}{r}$
• D. Some other value.

Answer 1

Answer: (A)

$\frac{1}{4\,\pi\,\varepsilon_0}\frac {qq_0}{r}$

Answer 2

Electric potential energy will be converted into kinetic energy.
