Consider a plate capacitor with a dielectric interface (\epsilon = \epsilon_0*\epsilon_r, thickness=d) tilted at the angle \alpha . Outside the interface \epsilon = \epsilon_0. Without dielectric interface is the field \vec{E}=E_0*\vec{e_z}.
Determine the E-field inside and outside the...
thank you !
I know that the moment of inertia of a disc is the moment of inertia as a cylinder but how do i discribe the rotation of the disc when it spins on a shaft at an angle alpha?
The shaft of the spinning top would rotate on the coat of a cone i guess...
yeah I did it before but my problem is that I don't know how to describe the x y and z values to put them in the moment of inertia
I used the definition below for I and put in the spherical coordinates
I hope you guys can help me with this problem..
A top in the form of a flat, circular disc spins on a shaft that is inclined at an angle alpha to the vertical.
Now I have to find the moment of inertia I for the disc about its centre on the shaft.
My attempt was building I with spherical...
