Homework Statement
Three concentric spherical shells ,r=1m ,r=2m and r=3m, respectively, have charge
distributions 2, −4, and 5 μC/m2.
Calculate the flux through r=1.5m and r=2.5m
Homework Equations
Since we are talking about Gaussian surfaces I assume that the flux at 1.5m is just the flux contained in the 1m shell.
I'm particularly having trouble figuring out what to do with the data. Given that the charge distribution is given in uC/m^2, I assume we need to multiply this by the surface area of each sphere to find the total enclosed charge (Qenc).
Then I have that flux = Qenc/ε0. But these answers seem way too high.
The Attempt at a Solution
SA1=4(pi)r2=4(pi)m2
Qenc1=4(pi)m2*2uC/m2=8(pi)uC
flux=8(pi)uC/ε0=2.84x106C
where ε0=(10-9/(36*pi))
