Points A and B have position vectors (3i + j)m and (5i + 4j + 2k)m respectively. A particle moves from rest at the point A to the point B under the action of a constant force F Newtons only. Given that the work done by the force in moving the bead from A to B is 34 Nm, find F.
I've found that [itex]|\textbf{F}| = \sqrt{68}[/itex], which is correct, but I'm supposed to find it in vector form: [itex]\textbf{F} = 4\textbf{i} + 6\textbf{j} + 4\textbf{k}[/itex]. How do I do that?
