Question

two uniform rods of the same length L and mass Mlying on an with separation d

Answer 1

thus linear density is p=M/L, const G = 6.6742e-11;

the rods are parallel;  

elementary force is a vector dF = G*(p*du)*(p*dv) *r/|r|^3, where r=(u-v, d) is vector connecting two elementary masses p*du and p*dv, u and v being coordinates of these masses respectively, |r|=√((u-v)^2 +d^2) is the distance between them;    

force F= G*p^2*∫ du *∫ dv (u-v, d) /√((u-v)^2 +d^2)^3 {u=0 to L, v=0 to L} =

= continue! Will you?

Answer 2

yes

Answer 3

... huh

Answer 4

Go on...

Seriously, that&#039;s not a question.

Answer 5

Look if you haven&#039;t bought the book yet, how can you expect to complete the homework.

I&#039;d bet my life the formula is in there.  This is AUGUST, for chrissake.  How in depth can you&#039;ve gotten?
