Hi,
I don't get what the conditions below exactly means.
Its which u they are talking about? Is the u the parent or children? Does it mean u = B? and the children are A,C,D?
if u is in the quadtree rooted by v:NW then u:x < v:x and u:y ≥ v:y;
Thanks,
2) Before I didn't draw it. But now I did draw it. its cos(60)? Because 20N acting 30º east of north and the other force is 20N acting 30º west of north
1) Direction the are going to the north?
2) Sorry, its cos(30) I overlooked the value. Should I do the whole calculation of it?
Ok I have revise the forces and vectors addtion again and I will come back in few days!
I think it should be like this?
1) Both forces are showing in the same direction and together it makes 40 N?
2) R^2 = 20^2 + 20^2 -2 * 20 * 20 * cos(50)?
Hello everybody
To calculate the flux for the electric field I need the gauss law. There are two formula one with the integration over some area and the other is Q/e0. When do I have to use which one?
Hi everybody,
I tried to solve this problem but somehow I don't get it really. What I have to do. What I also know in this context is if its the same charge it will not attract otherwise if its the opposite charge it will attract. How do I have to calculate each charge on the corner?
Question...
