A hanging potted plant is suspended by a cord from a hook in the ceiling. Draw an FBD for each of these:
(a) The system consisting of plant, soil, and pot;
(b) The cord;
(c) The hook;
(d) The system consisting of plant, soil, pot, cord, and hook. Label each force arrow using subscripts (for example, Fch would represent the force exerted on the cord by the hook).
