The 8.1 n weight is in equilibrium under the influence of the three forces acting on it. the f force acts from above on the left at an angle of with the horizontal. the 6.4 n force acts from above on the right at an angle of 46? with the horizontal. the force 8.1 n acts straight down what is the magnitude of the force f? answer in units of n. note i have already gotten this part, which is 5.66n, but i am having difficulties of answering the second portion of this problem, which is: what is the angle of the force f as shown in the figure? answer in units of

Explanation:

Given:

Observe the schematic showing the angle direction and magnitude of the forces acting on the center of the mass.

Here we find that there are 3 forces acting on a point and we can build a relation among the forces and the angle between them using Lami's Theorem.

Now, from the extreme left and extreme right term:

Now, for calculating force F:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
