Two particles, each of mass m, are connected by a light inflexible string of length l. The string passes through a small smooth hole in the centre of a smooth horizontal table, so that one particle is below the table and the other can move on the surface of the table. Take the origin of the (plane) polar coordinates to be the hole, and describe the height of the lower particle by the coordinate z, measured downwards from the table surface.
i. sketch all forces acting on each mass
ii. explain how we get the following equation for the total energy
(a) Find the scalar products î · î, ĵ· ĵ, and k · Ê.

- a. Prove the triple product identity Ax(B×C)= B(A·C)-C(A·B). Begin by adopting a Cartesian coordinate system. Without loss of generality, you may orient your coordinate system such that the x axis is along B, so that B = Bi. You then have the freedom to place the y axis in the plane defined by B and C.
