How are charges built up?

• Charges build up when the object that accepts the electrons becomes negatively charged.

• Charges build up when negative electrons are transferred from one object to another.

• All of the other statements are true.

• Charges build up when the object that gives up electrons becomes positively charged.

Which statement does NOT explain the Law of conservation of charge?

• The total charge remains the same within the system

• The total charges must all add up to 1

• Charge can neither created nor destroyed

  Submit

• Charges can be transferred from one substance to anotherSubmit

Which statement does NOT explain Coulomb’s law?

Use the mathematical equation of Coulomb's law.

F = k (q₁q₂/d²)

• If the distance between the charges increase the electric force will decrease

• If charges increase the electric force will decrease

• The electric force is inverse to the square of their distance.

• The electric force is proportional to the product of their charges

The unit of electric charge

• Coulomb

• Ampere

• Ohms

• Volt

Which of these does NOT describe the electrostatics law and Coulomb's law? Use the mathematical equation of Coulomb's law.

F = k (q₁q₂/d²)

• Like charges repel, Unlike charges attract

• Electric force is the product of the distance and their charges.

• Electric force is proportional to the product of the charges

• Electric force is inverse to the square of their distance.
