AI Thread Summary
The discussion focuses on the properties of an alternating electromotive force (EMF) with an angular frequency of 200 radians per second applied to large circular plates. Participants calculated the area and capacitance of the plates but expressed confusion about determining the electric field E(t) without current or charge present. The amplitude of the electric field, Em, and its actual form E(t) between the plates were also queried. The lack of provided EMF magnitude complicates the calculations further. Understanding the relationship between the electric field and the absence of current is crucial for resolving these issues.

The Question Reads: Discuss the propertoes of an alternating electromotive force with an angular frequency of 200 radians per seconf applied across to large circular plates of radius 0.10 m separated by a distance of 0.01m. Describe the electric field E(t) between the plates assuming no charges and current are present there. What is the amplitude of the electric field Em? What is the actual form of the electric field with the numbers between the plates E(t)?

I was able to calculate the area and the capacitance with ease but the next step I don't knwo what I would have to do I am thinking I have to find the Magnetic Field because the next question relates to the Magnetic Field. Yet the question says that there is no current present and in order to find the magnetic field you need the current HELP ME!1

They didn't give you the magnitude of the EMF?
 
Nope no EMF
 
Thread 'Collision of a bullet on a rod-string system: query'
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...
