1. The problem statement, all variables and given/known data Reading a journal from that crazy old retired physics professor on the hill, you stumble upon a scheme to generate high frequency (HF) radio waves (λ = 10 m). It requires generating an electric field that diverges from a point and increases in strength linearly with respect to distance from that point. (a) What type of common charge would create an oscillation if placed in this field? Explain why the others would not. (b) Could the charge be placed at rest at the di- vergence point and still oscillate? (c) What must the E-field strength coefficient be to generate the HF radio waves? (hint: does this really need to be a three dimensional prob- lem?) Extra credit (and possibly greater accolades) - How could such a field be generated? Known: the electric field is diverging from a single positive point charge. The lines all spread out and get further apart as they move from the center dot. 2. Relevant equations This is more of a conceptual problem so I don't know if there ARE any pertinent equations. 3. The attempt at a solution My first thought was to Google all the vocab that I don't understand such as "common charge" and what causes an oscillating point charge and write it down. That just left me even more confused. I also don't know what an E-field coefficient is. I have perfect attendance and take good notes I just feel like my prof. enjoys making everyone feel stupid. The averaged in my class is a 48%. :( Could some one please walk me through this or maybe set me in the right direction?
