Problem Set 9: Physlet 3

Three spherical shells (red, green, and blue) are located on the screen--you can only see the part of the sphere that is in the plane of the page.  A test charge is also shown that measures the electric field (in N/C) at that point (position is given in meters).  Calculate the flux through each spherical shell.  You can click-drag on the test charge to change its position.  Start


  1. Cannot determine.  There is not enough information given.
  2. red: 0.56 Nm2/C green: 4.0 Nm2/C and blue: 6.3 Nm2/C..
  3. red: 2.2 Nm2/C green: 16 Nm2/C and blue: 25 Nm2/C.
  4. 0 for all 3 shells.
