A Big Problem:
(a) sub-problem 1:
Assuming that a radio transmitter emits a radial pulse 'K' times a second, what would that frequency need to be in order to detect the doppler shift of an object traveling a 6000 m/s?
(b) sub-problem 2:
If one had a cathode ray source which was outputting an average of N electrons per second in a cone; how much charge over time could be deposited onto a 4 gram, round metal (assume copper, for now) surface which was traveling towards the cathode ray source at 920 m/s and is distance 'r' away from the cathode ray?
(c) sub-problem 3 (this one is easy):
Given that an electric field is generated from a source some distance below the cathode ray, knowing the charge that can be generated on the surface within a certain time period; how intense should it be in order to deflect the metal object at least some distance 'd' above the cathode ray source?
(d) overarching problem (not so easy):
Assuming a system was created to detect a metal object (using information from part a), spray the object with electrons to give it a charge, then given a small acceleration from a potential to alter the trajectory of the object away from or around the system; how quickly could part (a) and (c) be accomplished? (this is an engineering question)
(e) power problem:
How much power would a system that ran like this consume? Note that it's assumed that it's outputting a radio signal K times a second and looking for doppler shift above a certain range, when doppler shift is detected above that range it activates the cathode ray in the direction of the object and generates a potential which interacts with the electrons on the metal object.
Note: Not a homework problem... a truly crazy idea I had which probably isn't even technologically feasible. (It is physically possible!... I think)
Sub-problem (b) is a scattering problem and probably the main limiting feature to this idea. I'm not sure that enough charge could be deposited in a reasonable enough time frame for this idea to work. Presumably you might be able to control N, the number of electrons output through temperature and type of material, (I really have no clue, this is outside of my area of expertise).
If you've read up to this point, thanks for humoring me. What do you think of the idea? :)
