I proved that all even vectors in a circle than pull outwards have a net force of 0. I'm having trouble with odd vectors.
What I've managed to do so far:
I'm having trouble with doing it for cos, plus I don't know if I'm solving it correctly. Thanks
Well kind of, that is the one I used. We can use any one necessary. We weren't given any equation, we were just asked to prove it.
I proved it for n=3 with real angles, and by adding the vectors it's net force is 0. I also did this for n>3 when n is even. It's when n>3 and odd that I'm having trouble with.
No it doesn't have to be, as when I was proving when N was even I broke it up.
The question was this: All vectors exert forced of the same magnitude F. Calculate the net force on all the vectors when N is any integer greater than 3.
So yeah, I've done if for N=3 and N>3 when N is even. We can do anything to make it work. Thanks for your help so far ;D
