    Exploring the Possibility of a Unified Quantum Field Theory

    No. Each field has a certain value at each point of space time. For simplicity take the value one to indicate that there is a particle and 0 no particle. Then the idea that at any point only one particle is possible does not exclude the existence of many different fields. And a field by...

    Exploring the Possibility of a Unified Quantum Field Theory

    I see. Well, a field usually will not "occupy" space. They only assign a physical quantity to point of spacetime. As a classical example at each point you could have a value for the temperature, humidity, wind, etc. each being a different field. Now a quantum field will describe a certain kind...

    Why should it not be possible?

    Advanced Gauss's Law Question

    So can you express \sigma in terms of Q_{total}? For the \rho part you have to take Gauss surfaces inside the sphere as Matterwave said.

    Exploring the Possibility of a Unified Quantum Field Theory

    I think you missed to post the important point after "fact that". I don't get much sense out of your sentence this way.

    Solve Gauss's Law: 8.0 & -4.9 Charges in Uncharged Sphere

    \Phi=\frac{q}{\epsilon_0}=\frac{3.1\mu C}{8.85418782 \cdot 10^{-12} \frac{As}{Vm}}=0.35 \cdot 10^6 Vm=3.5\cdot 10^5 Vm = 3.5\cdot 10^2 kN m^2/C I had calculated with milli Coulomb before.

    Solve Gauss's Law: 8.0 & -4.9 Charges in Uncharged Sphere

    No it is 3.5\cdot 10^{11} Vm = 3.5\cdot 10^8 KN m^2/C. And from the data you gave (charges 8 mC and -4.9 mC) this is correct. I agree with sgd on that.

    Solve Gauss's Law: 8.0 & -4.9 Charges in Uncharged Sphere

    sgd is right. Seems i wasn't really awake when I tried to convert the units. But converting the units will only change factors of 10.

    Solve Gauss's Law: 8.0 & -4.9 Charges in Uncharged Sphere

    Does the numerical value of the answer fit? Look up SI units. There is no way to convert kiloNewton* meter^2 / Coloumb to Volt * meter

    Falling down a hole through the Earth.

    This is a hypothetical question, when you drill a hole through the Earth's core.

    Falling down a hole through the Earth.

    This data might help http://geophysics.ou.edu/solid_earth/prem.html" [Broken] Using this I get 37.25 minutes for a trip.

    Finding charge with mass, length and separation

    Welcome to the forum. First you should sketch the situation. Also include all forces acting on the balls.

    Solve Gauss's Law: 8.0 & -4.9 Charges in Uncharged Sphere

    You can never get the unit you gave. The Vm sgd gave is the correct unit.

    Calculating the Magnetic Field in Free Space

    x,y,z. You just have to find the right combination.
