4.1.1 Electric Charge

• What is electric charge defined as?

  Fundamental physical property
• Negative charge is carried by electrons
• Protons are located in the nucleus and carry a positive charge.


  True
• What is the fundamental physical property of electric charge?

  Causes matter to experience force
• What does it mean for electric charge to be quantized?

  Comes in discrete amounts
• Electric charge is conserved, meaning it cannot be created or destroyed
• How many protons or electrons does one coulomb represent approximately?

  $6.24 \times 10^{18}$
• Electric charge is a fundamental physical property of matter that causes it to experience a force in an electromagnetic field


  True
• Like charges repel each other

  True
• Positive and negative charges attract each other


  True
• The magnitude of the charge on a proton and an electron is the same, but the signs are opposite


  True
• The negative sign in Coulomb's Law indicates an attractive force


  True
• What are the two types of electric charge?

  Positive and negative
• What is the unit of electric charge?

  Coulomb (C)
• Where is the electron located in an atom?

  Orbiting the nucleus
• Positive charge is carried by protons located in the nucleus.


  True
• What does it mean for electric charge to be conserved?

  Cannot be created or destroyed
• Match the charge type with its carrier and location:

  Positive ↔️ Proton in nucleus

  Negative ↔️ Electron orbiting nucleus
• One coulomb represents the charge of approximately $6.24 \times 10^{18}$ protons or electrons
• The coulomb represents the basic unit of positive or negative electric charge
• What does it mean for electric charge to be quantized?

  Comes in discrete amounts
• Positive charge is carried by protons in the nucleus
• What is the charge of a single proton in coulombs?

  +1 C
• Coulomb's Law states that the electric force is directly proportional to the product of the charges and inversely proportional to the square of the distance
• Positive charge is carried by protons
• What is the symbol for electric charge?

  Q or q
• Which subatomic particle carries a negative charge?

  Electron
• Electric charge is a fundamental physical property that causes matter to experience forces when placed in an electromagnetic
• Like charges repel each other, while opposite charges attract.

  True
• Electric charge is quantized, conserved, and like charges repel.

  True
• A single proton has a charge of +1 C, while a single electron has a charge of -1 C.

  True
• What does the coulomb represent in terms of electric charge?

  Basic unit
• The symbol for electric charge is Q
• What happens to electric charge in a closed system?

  It is conserved
• One coulomb represents the charge of approximately 6.24 x 10^18 protons or electrons
• What is the value of the elementary charge (e) in coulombs?

  $1.602 \times 10^{ - 19} \, \text{C}$
• What is the approximate value of Coulomb's constant (k)?

  $8.9875 \times 10^{9} \, \text{N m}^{2} / \text{C}^{2}$
