By what factor is the electrical force between a pair of ions changed when their separation distance is doubled?

When the separation distance between a pair of ions is doubled, the electrical force between them decreases by a factor of 4. This is because the electrical force is inversely proportional to the square of the distance between the charges.


What happens when air uplifts rapidly causing electrical charges to form?

When air uplifts rapidly, friction occurs between air particles, leading to the separation of positive and negative charges. This creates electrical charges, which can result in lightning strikes or thunderstorms. The buildup of electrical charges may discharge as lightning bolts, illuminating the sky and producing thunder.


The electrical force between charges is strongest when the charges are?

The electrical force between charges is strongest when the charges are closest together. The force decreases as the distance between the charges increases according to Coulomb's Law.


What would the separation between two identical objects one carrying 1 C of positive charge and the other 1 C of negative charge have to be if the electrical force on each was precisely 1 N?

The separation between the two objects would have to be 1 meter for the electrical force on each to be precisely 1 N. This is based on Coulomb's law, which states that the magnitude of the electrical force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.


Is it true that the attraction will vary directly with the separation between the charges?

Yes, the force of attraction between two charges will vary directly with the separation distance. As the distance between the charges increases, the force of attraction will decrease, following an inverse square law.

What happens to the force between the charges when the separation distance is tripled?

The force between charges decreases to (1/9) of the original force when the separation distance is tripled according to Coulomb's Law. This is because force is inversely proportional to the square of the separation distance.


Who discovered a relationship between charges their separation and the force between the two charges?

Charles-Augustin de Coulomb discovered the relationship between electric charges, their separation, and the force between them. This relationship is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.


Do objects that have an excess number of negative charges have electrical energy or a chemical reaction?

Objects with an excess of negative charges have electrical potential energy due to the separation of charges. When these charges are allowed to flow, they create an electrical current, releasing this stored energy in the form of electrical work. While chemical reactions involve the breaking and forming of chemical bonds, the excess negative charges in an object do not typically result in a chemical reaction.


Are the coulomb forces between electrical charges conservative?

yes i think that electrical are to much


What kind of energy does separation of charges create?

Separation of charges creates potential energy, also known as electrostatic potential energy. This energy is stored in the electric field between the separated charges, and can be released when the charges are allowed to come together.


When the distance between two charges is three time far apart electrical force between the charge is?

Electrical forces are inversely proportional to the square of the distance separating the charges.


What happens to electrical force when distance between charges increase?

The electrical force between charges decreases as the distance between them increases. This is because the force follows an inverse square law relationship with distance, meaning that it weakens proportionally to the square of the distance between the charges.
