Law- finding the electric field from a symmetric charge distribution
Last time we talked about the procedure
one uses to find the elctric field via Gauss' Law.
(24-17P) A very long, thin wire has a uniform linear
charge density of 50 mC/m. What is the electric field at a distance
2.0cm from the wire?
(24-19P) A charge of -30mC
is distributed uniformly throughout a spherical volume of radius 10cm.
Determine the electric field due to this charge at a distance of a) 2.0cm
and c) 20.0 from the center of the sphere. (Yes, we're skipping part
