Questions and Answers

What type of quantity is the electric field?

  • Matrix
  • Tensor
  • Scalar
  • Vector (correct)

    • In the context of timedependent electromagnetic phenomena, why is the concept of electric field significant?

  • It helps in predicting charges at rest
  • It accounts for time delays in force interactions between charges in motion (correct)
  • It prevents the creation of electric charges
  • It increases the speed of light

    • What is the maximum speed at which information can travel from one point to another?

  • $\frac{1}{2}$ the speed of light
  • Speed of light (correct)
  • Speed of sound
  • $2$ times the speed of light
