NOTE 1The pixel pitch in the 45 degree diagonal direction is not the same as in the vertical and horizontal directions. Therefore, the diagonal pixel pitch is used when applying this table to measurements in the diagonal directionsNOTE 2There are three planes for determination of the resolution in e.g. LP/mm. It can be in the object space, on the sensor plane or in the image with a given output magnification. In most cases the resolution on the sensor plane is the important one. To get the right value for this situation the image file should be scaled to the Sensor dimension in which case the pixel pitch on the sensor is equal to the pitch of pixels in the image file.

The reversing ring such as the BR2A (Nikon, B&H) have a Nikon F mount on one side and a thread that matches the front of a camera lens on the other.

I will point out that lenses that use a 72mm (or 67mm) thread are not likely good candidates for using as a reversed lens. These are likely either zoom lenses or very wide. They are not likely designed to take the weight of the lens on the filter thread.

I recently ordered a reverse ring and turn out i ordered a wrong one. My camera is 7100 but i ordered D700 from ebay, i bet it won't be exchange but can i order something else to put it on my lens, so it make use for reverse ring 72mm for D700 use for my D7100?

You would likely be much better off with the BR2A from above and a Nikon 50mm f/1.8D lens. The D is important because it still has the f/stop ring and so you can manually stop down the lens. With lenses that don't have the f/stop ring (G lenses) you will find that you cannot change the f/stop on the lens after you have removed it from the camera.

Resolition is measured using edges, Siemens stars or other regular structures with aíncreasing frequencies. Units like LW/PH, LP/PH, or Cycles per pixel are independent of the sensor size and the pixel pitch. They just take the resulting image and its frequency content into account not caring about the size of each pixel. Dimensions like LP/mm, L/mm, or Cycles/mm require the knowledge about the sensor size / pixel pitch.The following table and explanation will be part of the upcoming revision of ISO 12233 and was created by Don Williams.
