What is true is that the field due to the point charge outside of the conductor will not be able to penetrate the shell i.e. there will be no field due to the external point charge anywhere within the conductor nor in the cavity: the field will be **killed off*& by the charges on the outer...
In Calculus II, we're learning about solids of revolutions and computing their volumes.
I'm unsure when to apply the appropriate methods and how to make the correct partitions.
Please tell me if my reasoning is correct:
The disk/washer method is applied when your partitions are perpendicular...
Historically, quantum mechanics, or wave mechanics, arose due to the anomaly that accelerating free charges ( electrons ) radiated EM waves. The quantisation theory provided a solution.
Quarks also have electric charge, and are moving at relativistic speeds, and bound in the nucleon.
As the...

Hello,
I would like to thank all of the contributors on this site. You have helped me in more ways than I can count. I am struggling with the following concept and was wondering if anyone could clarify this.
As the electron gets further away from the nucleus, its energy increases. This makes...
So I'm getting ready for an exam on tuesday, and I'm using each method for volumes of revolutions for every problem but I'm not getting the same answers. So, let's use this as an example:
y = 5x; the shaded region is from [1,2]
Using the disk method (about the x-axis) I find:
R(x) = 5x; r(x)...
