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. 1. FDG: the force the desk (D) exerts on the ground (G). 2. Fpp: the force the desk (D) exerts on the physics book (P). 3. FGD: the force the ground (G) exerts on the desk (D). 4. FHP: the force the history book (H) exerts on the physics book (P). 5. FPD: the force the physics book (P) exerts on the desk (D). 6. FPH: the force the physics book (P) exerts on the history book (H). 7. WD: the weight of the desk (D). 8. WH: the weight of the history book (H). 9. 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. All of the following relationships are correct. Which are correct due to Newton's Third Law? OFDG = FGD FPH OFHP OFPH = WH OFPD = FDP OFGD = WD + FPD OFDP = Wp + FHP
