Consider a coin of Question 20 . It is electrically neutral and contains equal amounts of positive and negative charge of magnitude 34.8 kC. Suppose that these equal charges were concentrated in two point charges separated by
(i) 1cm `(~(1)/(2)xx`diagonal of the one paisa coin`)`
(ii) 100 m (`~` length of a long building)
(iii) `10^(6)m` (radius of the earth). find the force on each such point charge in each of the three cases. what do you conclude from these results?

Explanation

To solve the problem, we need to calculate the electrostatic force between two equal point charges separated by different distances. We will use Coulomb's Law, which states that the force \( F \) between two point charges \( q_1 \) and \( q_2 \) separated by a distance \( r \) is given by:

\[ F = \frac{1}{4 \pi \epsilon_0} \frac{q_1 q_2}{r^2} \]

Since both charges are equal and denoted as \( q \), we can simplify this to:
