How can electric force be reduced?
Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.
What are the 2 factors the strength of an electric charge depends on?
The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them.
What are the factors that affect electric field strength?
▪ An electric fields strength is dependent on two things:
- Strength of the charge.
- Distance from the charge.
- Friction.
- Conduction (Direct Contact)
- Induction.

What happens to the electric force as charge increases?
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. If the charges come 10 times closer, the size of the force increases by a factor of 100. The size of the force is proportional to the value of each charge.
What two things affect the size of the electric force?
The size of the electric force between two objects is affected by the strength of the charge and the distance between the objects. Objects with strong positive and negative charges will have a greater electric force. As the distance between the objects decreases, the electrical force increases.
How two objects can be attracted due to an electric force even when both objects have zero net charge?
An electric force is exerted between any two charged objects. Objects with the same charge, both positive and both negative, will repel each other, and objects with opposite charges, one positive and one negative, will attract each other.
What will happen if two uncharged neutral objects are brought close together?
When two neutral objects come into contact–especially in a dry environment–electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged.
What happens when two objects rub against each other?
When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
Which force is present when two objects rub against each other?
Friction
Which charges are transferred on rubbing?
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.
What are the two factors that affect the frictional force between objects?
The factors that affect the friction between two surfaces are the weight of the object and the coefficient of friction of the surface.
What is it called when a force makes an object move away?
repulsion. noun. physics an electrical or magnetic force that makes things move away from each other.
Is normal force a push or pull?
For example, when a book is placed on a table, the normal force keeps the book from falling through the table. Gravity is pulling the book downward, but since the book isn’t actually falling, something must be pushing it up. This force is called the normal force.
