What is the size and electric charge of a raindrop mentioned in the given scenario?
Understanding the Electric Charge of a Raindrop
When it comes to raindrops, they can acquire an electric charge as they fall. In this specific scenario, we are provided with a raindrop that has a diameter of 2.5 mm and carries a charge of 15 picocoulombs (pc). This charge indicates the excess or deficit of electrons on the raindrop's surface as it descends. Let's delve deeper into the components involved:
Electric Charge:
Electric charge is a fundamental property of matter that determines the interactions between objects. It can be either positive or negative. In the case of the raindrop, the mentioned charge of 15 picocoulombs signifies that there is an imbalance of electrons on its surface.
Diameter:
The diameter of the raindrop is specified as 2.5 mm. Diameter refers to the widest distance across the raindrop, providing insight into its size in this context.
Charge of 15 picocoulombs:
The abbreviation "pc" stands for picocoulombs, which is a unit used to measure electric charge. A value of 15 picocoulombs indicates the magnitude of the charge carried by the raindrop. 1 picocoulomb is equivalent to 10^-12 coulombs.
In conclusion, the raindrop with a diameter of 2.5 mm and an electric charge of 15 picocoulombs exhibits an imbalance of electrons on its surface, leading to the acquisition of an electric charge as it falls. The interaction between the raindrop and its surroundings plays a crucial role in this phenomenon.
