oh okay. the theory confused me when it insisted 1/r. i think i got to clarify with the lab lecturer. i was sure it was 1/r^2 by that understanding. thanks ppl!

errr, how do i model the ring and a round electrode pressed onto a plane as? a point charge with a spherical shell? but that will give me E is proportional to 1/r^2. this is the part i do not understand..

oh thanks, it is clearer now. but how about the part of point vs 1d line vs 2dimentional sheet?

hi, i do not understand exactly wad you mean... is there any diagram i cud refer to?

Hi all, I was taught that E(field strength) is proportional to 1/r for a setup of a ring(earthed) and a positive electrode(in the centre of the ring). can anyone confirm this or guide me its derivation? thanks in advance!

hi all, am a confused-being after trying to solve this really simple question.. somewhere somehow my concepts are just not right ): Consider an airplane flying with a velocity of 60m/s at a standard altitude of 3km. At a point on the wing, the airflow velocity is 70m/s. Calculate the...
