I know how to add harmonic oscillations on the same axis but i was wondering why can i do it? If i have x1(t)=Asin(w1t +fi1) and x2(t)=Bsin(w2t +fi2), why can i say that the resultant motion is x=x1+x2. Once again I am not interested in the solution because i know how to derive it but how to...

Yes, I agree with u. U have been very helpful. It seems so obvious now, I don't know why has it been so hard for me to notice. I just wanted it 2 be more complicated:) Once more, big THANKS!

Yes I am aware of the facts, but I am interested in the physics behind them...

Doc Al, yes i would agree with u only if there is charge inside that is producing that field. U can use ur assumptions only if the r>R, where R is the radius of the sphere and r is the point in which u r observing ur field. As for the comment above, I must admit it is a bit 2 advanced for me...

Yes the shell is empty, but the surface is charged.

I've read many times now that the electric field inside a spherical shell is zero and all explanations of that fact have been based on imo false interpretation of the gauss law. The law itself says no such thing, atleast not explicitly. It merely says that the flux is zero. The only thing i can...
