Tension on an inclined plane

 

Consider a block on a ``frictionless'' inclined plane. We'll talk about friction in a little while so don't get too bothered by this term. Basically it means a very very very well greased surface, so that there is no force acting along any direction on the surface of the plane. We have this block of mass m that is attached by some string to a force meter. We want to know how much force is registered by the meter. If the angle tex2html_wrap_inline673 that the inclined plane makes with the horizontal is zero then this force will be zero. But for other angles what is the answer?

Let's follow the handy-dandy rules of above to quite effortlessly solve this problem. Once you've gone through this once. You should try to solve it again without looking.
