What happens to the force between 2 charges if the distance between them is halved?

Explanation: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

What is the formula of distance between two charges?

If the electrostatic charge and force are known, then it’s possible to use Coulomb’s Law to find the distance between the objects. So, the distance between objects r is equal to the square root of the Coulomb constant ke times the charge of an object q1 times the charge of the other object q2 divided by the force F.

What is the force between two charges?

Coulomb’s law, or Coulomb’s inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force.

How do you find the initial force between two charges?

Answer: 5F / 16 Solution: The initial force between the two charges separated by a distance d is F=2kQ2/d2. After touching, the charges become Q/2 and 5Q/4 and the force is 5kQ2/8d2=5F/16. 2. A particle with charge 2 µC is placed at the origin.

What is the force of attraction between two charges?

Explanation : The force between two charges is given by Coulomb’s law. It states that “ like charges repel and opposite charges attract each other, with a force proportional to the product of the charges and inversely proportional to the square of the distance between them”.

What is the magnitude of the electrostatic force between point charges?

The magnitude of the electrostatic force F between point charges q1 and q2 separated by a distance r is given by Coulomb’s law. Note that Newton’s third law (every force exerted creates an equal and opposite force) applies as usual—the force on q1 is equal in magnitude and opposite in direction to the force it exerts on q2.

How does a magnet interact with a moving charge?

Magnetic Field. Interaction of magnetic force and charge – The moving charge interacts with the fixed magnet. The force between them is at a maximum when the velocity of the charge is perpendicular to the magnetic field.
