Answer

The electrostatic force between the charges is approximately \( 2.115 \times 10^{16} \, \mathrm{N} \). When the charges touch, they share the total charge of \( 27.09 \, \mu \mathrm{C} \) equally, resulting in each charge becoming \( 13.545 \, \mu \mathrm{C} \). When the system is earthed, about \( 4.62 \times 10^{7} \) electrons flow in or out to neutralize the charge. If the charges are not earthed, they retain the total charge of \( 27.09 \, \mu \mathrm{C} \). Approximately \( 1.90 \times 10^{7} \) electrons moved from one charge to the other when they touched.

Did you know that the concept of electric charge has roots dating back to ancient Greece? Philosophers like Thales discovered that rubbing amber (fossilized tree resin) with fur caused it to attract lightweight objects, leading to the early principles of electrostatics! The modern understanding of electricity began to crystallize in the 18th century with luminaries like Benjamin Franklin and Charles-Augustin de Coulomb. In the real world, electrostatics is everywhere! From dust sticking to your screen to the shocks you feel after walking on a carpet, these principles govern numerous everyday phenomena. In industries, electrostatics plays a crucial role in spray painting, powders, and electronic component manufacturing, ensuring a cleaner and more efficient process. Understanding these charges can help avoid static-related issues and improve product quality!
