 Emeritus Sci Advisor HW Helper Thanks PF Gold P: 11,688 Use the fact that $\vec{F} = (\vec{F}\cdot\hat{a}_x)\hat{a}_x + (\vec{F}\cdot\hat{a}_y)\hat{a}_y + (\vec{F}\cdot\hat{a}_z)\hat{a}_z$. Calculate $\vec{F}\cdot \hat{a}_x$ using the various dot products you listed above. Then convert from the spherical variables to the Cartesian variables.
