5.x05一长直导线通有电流I1,其旁放一直导线AB,通有电流I2,二者在同一平面上,位置关系如图所示,其中a,b已知,求导线AB所受的安培力.
6.x05有一同轴电缆由无限长金属实心圆柱体和厚度可不记的金属圆筒组成,半径分别为R1和R2,通有等大反向电流I,试计算（1）r

F=£dF(上下限a,b)=uI1*I2/2§ ln(b/a)
6.(1)I=(r^2/R1^2)*I 再用安培环路定律即可(2)(3)同理; 1年前

1.Hi,long time no see;
2.Yeah,long time no see.This few days you are doing?
3.Oh,I these days were in the us play,there
4.Look!There's a man coming towards us!
5.Hi,guys!I'm XXX
6.It's incredible!His long and just like you!
7.Not surprisingly,I was just his cloning human body just.
8.You grow and he seems oh!That,what do you have in common?
9.As you can see,our looks very similar.
10.Well.
11.Secondly,we still have the same genetic gene.
12.Really?
13.Yes.Not only that,we still have the same blood type.
14.That's amazing.That you all have what differences?
15.Yes.First of all,our age is different.
16.See come out.
17.Secondly,we have different growth experience,and then make the different personality,different thought patterns.
18.Of course,environment,which affects the person's life?
19.But,no matter how,in line with the human moral speaking,we are determined to human cloning method,even if you again good,you also can't lies in the world from,hurry up disappear!
20.Well,I'll be disposed of,886.
