So this is what I have now, the answer I'm getting is extremely small, could someone please just check over my work to see if I have made any errors... Thanks
\begin{gather*}
C=17pF=1.7\times10^{-11}F\\
\lambda=550nm=5.5\times10^{-7}m\\
c=3.0\times10^8m/s
\end{gather8}...
Hi all, I've managed to solve the following question but the answer I'm getting doesn't seem right...
What inductance must be connected to a 17 pF capacitor in an oscillator capable of generating 550 nm (i.e. visible) electromagnetic waves? Comment on your answer.
To solve it I just...
Hey all, I'm working on this question for my homework. Can someone please help me get it under control, I read it and all I can say is 'huh'?
In a television picture tube, electrons are accelerated by thousands of volts through a vacuum. If a television set were laid on its back, would...
Hey all, I'm not sure where to start on this question. Any ideas would be spectacular.
A tiny conducting ball of mass 1.00 g and charge 20.0 times 10^{-6} is hung from a non-conducting, massless thread. The electric field of magnitude 10^3N/C existing in this region is uniform and...

So following your advice this is what I have come up with but I can't seem to solve the proof
\begin{equation*}
\begin{split}
F_{net_{x}}=0
\\ 0=F_c+T_x
\\ 0=\frac{kq^2}{L^2}-L\sin\theta
\end{split}\end{equation*}
and
\begin{equation*}
\begin{split}
F_{net_{y}}=0
\\...
Help
I too am working on a similar question. For mine it is asking for a proof that...
x=(\frac{2kLq^2}{mg})^{1/3}
So far this is what I have
\begin{equation*}
\begin{split}
F_{net}=0 \\
0=F_c+F_g+T \\
mg+\frac{kq^2}{x^2}+T=0
\end{split}
\end{equation*}
I'm not sure where...
Solution?
Hey all, totally bringing this up from the thread graveyard, but I too am having the same problems with this question. I understand where Doc Al is comming from but I still don't have a Θ1 to go from. Any help with this would be more then amazing.
