Questions and Answers

What is the unit of electric flux density?

  • C/m2 (correct)
  • Amperes
  • Coulombs/m2
  • Coulombs

Which property of electric flux states that it is independent of the medium?

  • It originates from positive charges and terminates on negative charges
  • Field lines never intersect each other
  • Its magnitude depends solely on the charge from which it originates
  • It is independent of the medium (correct)

What happens to the electric flux lines in the absence of negative charges?

  • They loop back to the positive charge
  • They extend indefinitely and radially towards infinity (correct)
  • They end abruptly
  • They form a closed loop
