A wrench .9m long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of (0,1,3) at the end of the wrench. Find the magnitude of the force in newtons needed to supply 100 J of torque to the bolt.

This is the formula i have:

T=|r x F| Can anybody point me in the right direction?

T=100J

r=.9j

F=F (0i+1j+3k)/sq root 1^2+3^2)

Replace the values on the formula and solve for F.
