The correct answer is 270N but I don't know how to get there.

Here are some of the equations we can use but if you know of others feel free to mention them.

T=1/f

f=1/T

v=(square root)F/(m/L)

Fn=nv/2L

Thanks for the help and please indicate which equation you chose if you end up picking one of the ones I have above.

**bobpursley**, Wednesday, July 13, 2011 at 9:41pmfreq*lambda= v=sqrt(F/linearmassdensity)

lambda= 2*length= 2* mass/(massdenstiy)

= .028/(.035) meters=.8m

solve for tension F.

100*.8=sqrt(F/.035)

6400*.035=F=224N

recheck my work to see if there is an error, I dont see it.
