Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of the following statements about electric charge is true?
Like charges attract, opposite charges repel.
Electric charge is created and destroyed in reactions.
Electric charge is quantized, meaning it comes in discrete units.
Only positive charges can move in a conductor.
2. The direction of an electric field at a point is defined as the direction of the force on a:
negative test charge.
positive test charge.
neutral test mass.
electron.
3. The unit of electric charge is the .
4. Electric field lines originate from charges and terminate on charges.
5. Electric potential is defined as the electric potential energy per unit .
6. Describe the relationship between electric field strength and electric potential.
7. A point charge of +5.0 μC is placed at the origin. Calculate the electric field strength at a point 0.50 m along the positive x-axis. (Coulomb's constant k = 8.99 x 10^9 Nm^2/C^2)
8. If the electric potential at a certain point is 12 V and a charge of 3.0 C is moved to that point, what is the electric potential energy of the charge at that point?
9. Electric field lines can cross each other.
True
False
10. The electric potential energy of a charge increases when it moves against the direction of the electric field.
True
False
