Question
Why can one ignore quantisation of electric charge when dealing with macroscopic i.e., large scale charges?
Solution
When compared to an electron's charge, e = 1.6 x 10-19C, charges at the macroscopic level are huge. There are about 1013 electronic charges in just 1 nC of charge. Therefore, the quantization of electric charge is irrelevant at this high scale since charge might take on a continuous value instead of a discrete integral multiple of e.

Consider a coin of Example 1.20. 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 seperated by (i) 1 cm `(∼ 1/2 xx "diagonal of the one paisa coin")`, (ii) 100 m (~ length of a long 6 building) and (iii) 106 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?
Two fixed, identical conducting plates (α and β), each of surface area S are charged to –Q and q, respectively, where Q > q > 0. A third identical plate (γ), free to move is located on the other side of the plate with charge q at a distance d (Figure). The third plate is released and collides with the plate β. Assume the collision is elastic and the time of collision is sufficient to redistribute charge amongst β and γ.
- Find the electric field acting on the plate γ before collision.
- Find the charges on β and γ after the collision.
- Find the velocity of the plate γ after the collision and at a distance d from the plate β.
