Thanks, everybody. Not sure i understand all your answers but enough to get the gist.

Hi, So i can accept that photons are virtual particles for the electromagnetic force but i have a question. Considering two stationary point charges. There are photon-like particles exchanged between them to produce the force? If so then placing a double slit between them should create some...

just an idea but if you have two particles with negligible mass, in Newtonian physics if they experienced a force they would have infinite acceleration >> they have to be infinitely far away if you add some more conditions like speed of light etc ... well mass will eventually become...

Thanks :) That was what i was looking for

kinda a shot in the dark, but maybe ifndef = if not defined? like python

assuming no loss for friction horizontal velocity = 50km/h time = 10 secs distance = vel*time

its 42

Yeah F=(1/(4∏ε))*(q1*q2/r2) so when q1 is halved, F is halved say A had and original charge of q0 A and C now have a charge of 1/2 q0 C touches B the total charge on both is q0 + 1/2 q0 as equal surface area => evenly distributed again, then sub into your formula

Yup :) The assumption for a 'perfect conductor' is that it distributes uniformly Read this if ur interested http://en.wikipedia.org/wiki/Faraday_cage

Hi, I just completed an assignment modelling an atom with one electron. The model was very simple, assuming that only coulombs law applied, then solving for standing wave solutions to the Schrodinger equation to find ionization energies. I was astounded how accurate it was. i thought it would...
