Question

What is the smallest electric force between two charges placed at a distance of 1.0m?

Answer 1

Answer:

on and off is switching is the smallest electric force

Answer 2

Given: Distance between two charges $(r) = 1m$

Find: The smallest electric force between two charges.

Solution:

Let's assume charges are Q and q

Force between two charges is given by

                    $F = \frac{KQq}{r^2}$

For Force to be minimum Q and q should be minimum.

We know that,

          The smallest charge  of electrons $= 1.6\times 10^{-19} C$ exist in nature.

So,  we have to choose electrons for both charge particles then force will be minimum.

                       $q_1_(min)= q_2_(min)= e^{-} = 1.6\times 10^{-19}$

                      $F_(min) = \frac{(9\times 10^9)(1.6\times 10^{-19} C)(1.6\times 10^{-19} C)}{1^2}$

                               $=2.304 \times 10^ {-28}N$

Thus,

The Smallest electric force between two charges is $=2.304 \times 10^ {-28}N$
