**drwls**, Tuesday, June 7, 2011 at 8:02amLet the direction of the 1 n vector be up (+y direction). The components of the resultant are:

1 n: 1 j

(j is a unit vector in +y direction)

2 n: -1 j + sqrt3 i

(i is a unit vectyor in +x direction)

3 n: -1.5 j -(3/2)sqrt3 i

vector sum:

-1.5 j + -(1/2)sqrt3 i

magnitude = sqrt[2.25 + 0.75)= sqrt3
