Worksheet: Charge Contained on a Plane Surface

Q1:

The electric flux through a square-shaped area of side 5.0 cm near a large charged sheet is found to be 3 . 0 0 × 1 0 5 N⋅m2/C when the area is parallel to the plate.

Find the charge density on the sheet.

  • A 3 . 1 × 1 0 1 3 C/m2
  • B 2 . 5 × 1 0 1 3 C/m2
  • C 3 . 5 × 1 0 1 3 C/m2
  • D 2 . 1 × 1 0 1 3 C/m2
  • E 3 . 9 × 1 0 1 3 C/m2

Q2:

A infinite sheet of charge has a uniform charge density of 18.0 µC/m2. What is the magnitude of the electric field due to this charge at a point just above the surface of the sheet?

  • A 4 . 6 0 × 1 0 6 N/C
  • B 0 . 3 2 2 × 1 0 6 N/C
  • C 6 . 5 5 × 1 0 6 N/C
  • D 1 . 0 2 × 1 0 6 N/C
  • E 7 . 4 0 × 1 0 6 N/C
