Can anyone explain the concepts behind dielectric material inside a capacitor. Why is the capacitor able to store more charge exactly? Thanks!

AI Thread Summary
Dielectric materials in capacitors enhance charge storage by polarizing their molecules in response to the electric field generated by the capacitor plates. This polarization reduces the effective electric field between the plates, leading to a decrease in voltage for a given charge. As a result, the capacitance increases, as capacitance is defined by the relationship C=Q/V. The presence of a dielectric allows capacitors to store more energy without increasing their physical size. Understanding these principles is essential for optimizing capacitor performance in various applications.
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question.
Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point?
Lets call the point which connects the string and rod as P.
Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
F1=(5000+200)g=5200*10=52000N --> F2=(5000+100)g=5100*10=51000N ?
