Project #39169 - physics 2

Consider a thin, spherical shell of radius 16.0 cm with a total charge of 28.4 µC distributed uniformly on its surface.
(a) Find the electric field 10.0 cm from the center of the charge distribution.
magnitude   Correct: Your answer is correct. MN/C
direction  Correct: Your answer is correct.

(b) Find the electric field 23.0 cm from the center of the charge distribution.
magnitude   Incorrect: Your answer is incorrect. 
For points outside the sphere does it matter if the charge is on the surface or at the center? MN/C
direction  Correct: Your answer is correct.

A uniformly charged, straight filament 5.10 m in length has a total positive charge of 2.00 µC. An uncharged cardboard cylinder 4.60 cm in length and 10.0 cm in radius surrounds the filament at its center, with the filament as the axis of the cylinder.
(a) Using reasonable approximations, find the electric field at the surface of the cylinder.
magnitude   kN/C
direction

(b) Using reasonable approximations, find the total electric flux through the cylinder.
