2: The drawing shows two books at rest on top of a desk. The history book is on top of the physics book, as shown. Labels for the magnitudes of relevant forces are listed below in alphabetic order. FDG : the force the desk (D) exerts on the ground (G). FDP : the force the desk (D) exerts on the physics book (P). FGD : the force the ground (G) exerts on the desk (D). FHP : the force the history book (H) exerts on the physics book (P). FPD : the force the physics book (P) exerts on the desk (D). FPH : the force the physics book (P) exerts on the history book (H). WD : the weight of the desk (D). WH : the weight of the history book (H). WP : the weight of the physics book (P). Begin by creating a free-body diagram for each of the objects, and then answer the questions below
