A ring of radius 5 m lies in the x,y plane, centered on the origin. The portions of the ring in the first and third quadrants have a mass density of 11.7 kg/m, while the portions of the ring in the second and fourth quadrants have a mass denisty of 8.5 kg/m. Find the z-component of the gravitational field due to the ring at a point P on the z-axis at a distance 6 m from the origin. Use G = 6.673e-11 N*m^2/kg^2 9z =

please follow instruction do not do it other way follow guess method only please    Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work. This part is very important, since you will allow you to verify thatwhat you do is…

Please explain the concepts on how to work these types of problems out. These are practice problems.Thank you for  your help.
