A region in space containing cargo which is distributed spherically so that the stocking load ρ is given by the equotations:
ρ = a for r<=R/2
ρ = 2a(1-r/R) for R/2<=r<=R
ρ=0 for r>=R
The total charge Q is 3*10^-17 C, the radius R of the overall distribution is 2*10^-14 m and a is a constant which has dimensions of C / m^3. Determine the constant a as
function of Q and R and the numerical value. b) Using the
Gauss's law find an expression for the measure of the electric field as a function of distance r
from the center of distribution. Do this separately for each of the three areas.
Make sure that your results agree with the borders of the areas. What fraction of
total load is contained within the region r<R/2?i spent like 3 hours to solve this, but no success
