In summary, the question discusses the properties of an alternating electromotive force with an angular frequency of 200 radians per second applied across two large circular plates of radius 0.10 m separated by a distance of 0.01m. It asks for the description of the electric field E(t) between the plates assuming no charges and current are present, the amplitude of the electric field Em, and the actual form of the electric field with the numbers between the plates E(t). The conversation also mentions the calculation of area and capacitance, and the confusion about finding the magnetic field without the presence of current.

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?
