I solved the problem using Laplace's Equation - the only problem is the Dielectic aspect of the shell. I suppose my boundary condition (ii) above:
(ii) (dVin/dr - dVout/dr)|r=R = -(surface charge density)/epsilon-knot
is wrong? Should I just change the epsilon-knot to the epsilon of the...
THANK YOU very much for your response.
Yes, I agree. I think I need to solve Laplace's Equation in spherical subject to the
boundary conditions:
(i) Vin = Vout
(ii) (dVin/dr - dVout/dr)|r=R = -(surface charge density)/epsilon-knot
(iii) As r-> infinity , V-> 0
Does this sound right to you...
Homework Statement
I have a question about an upper-division E&M HW
problem I'm stuck on. Any help would be GREATLY APPRECIATED!
Problem Statement:
An insulating spherical shell of radius R was set up to have a potential
on its surface of V=A*cos^2(theta), where A is a constant...
Thank you very much. I see. So the simple explanation is that we just observe all the wavelengths of visible light->white. What do you think about the red-hot poker example?
Do you think that the sun's radiation is just so much stronger than the poker's, so that's why with the poker we only...
Homework Statement
By Wien's we can determine that the max wavelength radiated by the sun is around 500 nm.
How does this compare to the apparent color of the sun? Attempt to explain this discrepancy.
