Question

When the charge of $3\text{C}$ is placed in a uniform electric field, it experiences a force of $3000\text{N}$ within the influence of this field, potential difference (in volt) between two points separated by a distance of
$1\text{cm}$ is (Give your answer in integer value)

Answer 1

Given :
$q=3\text{C},F=3000\text{N},r=1\text{cm}\text{or}0.01\text{m}$

We know that, $E=|\frac{dV}{dr}|$ Or $|\Delta V|=Er$

Substituting the data given in the question we get,

$\Delta V=1000\times 1\times {10}^{-2}=10\text{V}$

Accepted answer : $10$
