solve 1 and 2

Gravity Force Vectors Three buildings (each with a mass of 7) are arranged in an equilateral triangle with the centers of the buildings separated by a distance d. The magnitude of the net gravity force on each building (due to the other buildings) is Pyyer. Solution: This solution uses a coordinate system with 2 of the masses on the x-axis. One gravity force vector points in the x-direction. The other force vector makes a 60 angle with the x-axis. Use trigonometry to calculate the components of the net force: Fnaz = F + F cos 60 Frety = F sin 60 Calculate the magnitude using Pythagorean Theorem: Fret = 4/(F + Fcos 60)? + (F'sin 60)? Factor F out of the square root: Fuet = F4/(I + cos 60)? + (sin 60)? 2 | = Gm". Plug in 2 Pa = oe Ja + cos 60)? + (sin 60)? 1 3 points Pm ee Formula Answer Formula 3 points - Answer Po
