  • Question

  • A vacuum parallel plate capacitor is charged. The field between the plates is 2 x 104 V/m. If the space between the plates is filled with a material having ?r = 10, then the value of field in the dielectric will be


  • Options
  • A. 2 x 103 V/m
  • B. A vacuum parallel plate capacitor is charged. The field between the plates is 2 x 104 V/m. If the spx 104 V/m
  • C. 210 x 104 V/m
  • D. 2 x 105 V/m

  • Correct Answer
  • 2 x 103 V/m 

    Explanation
    D ? ?rE. The flux density is the same.

    Since ?r has become 10 times, E decreases by 10 times.
