Can you give me a clear derivation of electron electric field intensity which is placed in origin and oscillating in simple harmonic motion, at a distance "r" in the positive x direction.

THis should be in E&M textbooks (e.g. Griffith or Jackson). I'm away from my books at the moment.

well thanks for your reply

 

But I cant get it

 

Now please dont tell me to see some books because I dont have enough books on EM.

 

Can you derive it for me.

 

 

I've derived it but I'm not sure is it correct or not, please help me

Derivations aren't the sort of thing that lend themselves to posts — there are lots of steps and equations to write up.

Ok I can understand it

 

My aim was to calculate it and to see really that field are really moving.

 

 

It will be my pleasure if you can tell me that where I can get it over internet
