A is the answer to this question. The electrostatic force is known to be a branch of physics that will deal with different electrical charges that are already at rest. There are different reactions that may occur depending on what the electric charge will be exposed to.
For example, if there would be one positive and one negative, they would attract each other. If there is one positive and another positive, this means that the two things will repel each other. One example of this is when you repeatedly rub your carpet and there may be fibers that may start to become attracted by the clothes that you are wearing or even your slippers.
B is the answer to this question. The superposition principle will make sure that you can find the right net force and then assign this to 0 so you can get the results that you need. There are two types of charges namely positive and negative. When two the same types meet, they would repel each other but if two opposite sides meet, they would attract each other.
When the different particles attract each other, they form atoms which are vital for the creation of different forms of energy. An atom may only be just a particle but many atoms will form more vital parts of different items.
In chemistry, an elementary charge is most commonly denoted as an e or a q. According to the formal definition, it is the electric charge that a single proton carries, or it is equal to the magnitude of the electric charge that which a single electron causes.
This means that we do not take into account the sign of the charge, rather the magnitude only. This charge, is referred to as the elementary charge, which is the smallest multiple. Greater charges usually exist as multiple of this elementary charge which is also referred to as e, and it has a fixed elementary value.
In Chemistry, Q stands for the reaction quotient.
The reaction quotient Q, plays a major role in a chemical reaction. It can be used to determine the value of the products and reactants at any point in a chemical reaction.
It is also used to determine the direction a chemical reaction is most likely going to follow, if the value of the products and reactants are given.
When Q is compared with K ( equilibrium constant), it is easy to tell the direction a chemical reaction will go.
If Q < K, the reaction will move forward.
If Q > K, the reaction will move in reverse.
If Q= K, the system is at equilibrium.
