## Calculating the Coulomb Force on Two Electrically Charged Objects

In one of the new question areas in physics, hydroelectric power plants are built using waterfalls. The PLTA produces a power of 16,292.5 kW. The hydroelectric plant converts 95% of its energy from water falling from a height of 125 meters. The density of water is known to be 1000 kg/m³ and g = 9.8 m/s². Complete eruption and mass falls…use the road!!! Difference Between Complete Conversion and Incomplete Conversion What is the relationship between electric charge and electric current in a conductor? The formula is fish 1.5 meters deep in the pond. If the density of water is 4200 kg per cubic meter and the speed of gravity is 0.8 m/s², what pressure did the fish experience in 1785 according to the French physicist Charles Augustine Coulomb? The electric force between two charged particles. His research is known as Coulomb’s law.

In the Kemdikbud-e module report, Coulomb’s law states that “The magnitude of the attractive or repulsive force between two electrically charged objects is directly proportional to the multiplication of the product of the two charges and inversely proportional to the square of the distance between the two. cost”.

According to three dimensions, Coulomb’s force or Coulomb’s law is similar to the gravitational force, these two forces are forces that are inversely proportional to the square of the distance and are classified as natural forces.

Coulomb forces are divided into three categories, including Coulomb forces between two point charges, Coulomb forces of internal charges, and Coulomb forces of nonlinear charges.

Two electric charges repel and two electric charges attract. In this case, it means that a repulsive or attractive electric field is created between two electric charges.

The standard value of 9 x 109 N m2 C-2 only applies to cargo in vacuum or air, the value is different for other media.

F is positive if q and q1 have the same sign. The positive F sign indicates that the two charges do not repel each other. Conversely, if the negative sign represents attraction to each other

The electrostatic force F is a vector quantity, so the function must fulfill the conditions to affect a vector quantity. This means that if there are multiple charges, the net force experienced by one charge is the result of the superposition of the forces on the other charges.

The Coulomb force q1 acting on charges q2 and q3 is F = F12 + F13. If the direction to the right is positive and the direction to the left is negative, the magnitude of the Coulomb force on the charge is:

Understanding Combination Resistor Circuits – Resistors or resistors can be combined into one to produce a resistance value. When assembling resistors, there are circuits that are made in series and some are made in parallel. However, there is one more form of circuit, namely a mixed circuit (series and parallel). […]To explain Coulomb’s law, the force (F) exerted by one point charge on another point charge acts on the line connecting the two charges.

1 Coulomb’s Law The force (F) exerted by one point charge on another point charge acts on the line connecting the two charges. The magnitude of the force is inversely proportional to the square of the distance between them and directly proportional to the product of the two charges. +R

2 When calculating by Coulomb’s law, the sign of the charge is usually ignored and the direction of the force is determined based on the pattern, whether the force is attractive or repulsive.
