10.6 Electric Charges and Fields

• The total amount of electric charge in the universe is conserved


  True
• Match the charge type with its property:

  Positive Charge ↔️ Attracts negative charges

  Negative Charge ↔️ Attracts positive charges

  Like Charges ↔️ Repel each other
• The Coulomb constant is approximately 8.99 x 10^9 N⋅m^2/C^2.
• Order the steps in describing an electric field:

  1️⃣ Define the region of space around a charged object

  2️⃣ Represent the field using electric field lines

  3️⃣ Show the direction and strength of the electric force
• What is an electric field?

  A region of space
• What is the equation relating electric force, charge, and electric field strength?

  $F =$$q E$
• What do electric field lines represent?

  Direction and strength
• What are the two types of electric charges?

  Positive and negative
• What does Coulomb's Law describe?

  Force between charges
• What do 'q_1' and 'q_2' represent in Coulomb's Law?

  Charge magnitudes
• What is the relationship between charge magnitude and force in Coulomb's Law?

  Larger charge, greater force
• Match the charge type with its field properties:

  Positive charge ↔️ Field lines point outward

  Negative charge ↔️ Field lines point inward

  Strong electric field ↔️ Field lines are closer together

  Weak electric field ↔️ Field lines are farther apart
• Match the charge type with its field direction:

  Positive ↔️ Away from the charge

  Negative ↔️ Toward the charge
• The magnitude of the electric field determines the strength of the force on a charged object.


  True
• Electric fields are represented using field lines, which illustrate the strength and direction of the electric field
• Match the property with the correct charge:
