Thanks for the fast response. What does double-valued mean? Where does 2d come from (I thought we were only dealing with the length d!)? I think what you said could really help but I don't understand it! If you could rephrase what I quoted above, it would be really helpful.

Homework Statement A point charge +q is located a distance d from one end of a uniformly charged rod. The rod has total charge +Q and length L. (The rod and the point charge are each held fixed in place.) What is the force on the point charge due to the rod...

Thanks for the help, guys!

I just realized that my last response makes it sound like I solved the problem. I actually drew the directions correctly on my FBDs, but I wrote them out wrong on the forum. Thanks for the corrections, any more help is appreciated :)

Oops, I've said my directions completely wrong! The small block has a frictional force down the ramp, a normal force up and perpendicular to the ramp, and weight downward.

Homework Statement A small block of mass m rests on the rough, sloping side of a triangular block of mass M which itself rests on a horizontal frictionless table as shown in the figure. http://s7.photobucket.com/albums/y252/mikey555/?action=view&current=GIANCOLIch05p033.jpg (edit: image...
