I have just watched a very interesting way of multiplying 2 numbers together, but i wonder if anyone could explain to me why it works. here is the link Calculating technique - 5min - Video cheers gabrown

Cheers guys, I think i understand (think i was being a bit dumb) getting confised about my boundary conditions.

Edited.

Hi, I was wondering if anyone could help me solve or even know the type of the differential equation below d2x/dt2= k*dy/dtSorry I also have d2y/dt2= -k*dx/dt where k is a constant. I need it to find the position x when looking at a particle going through a magnetic field. Thanks very...

No ideas?

I may have gotten confused. I don't have the book I looked at on me, but the one i am referring to is PROBLEMS AND SOLUTIONS ON ELECTROMAGNETISM page 581 the problem is 5019 part b. I will try and post it tomorrow when i get the book to explain where my confusion is

Can i ask a related question, If we have two charges that are moving highly relativistically in a straight line, I have been told (and looked in the textbook) that they will repel to a certain distance and stay at that distance (or the force drops to very small), now I am concerned because...

Homework Statement I am wanting to get position (x and y) of a particle moving in a magnetic field as a function of time. So, we have a particle of mass m, charge q, velocity (Vx,0,0) moving in a magnetic field (o,o, Bz) starting at t=0 as (0,0,0), what is X(t) and Y(t). Homework...
