used. Using the value logg 2 = GOSIS, wefind a capacity of 231 electrostatic units per unit length. Thus a cable2000 miles in length has a capacity equal to that of a sphere of radius2000 X 231 miles, i.e., of a sphere greater than the earth. In practical units,the capacity of such a cable would be… … Fig. ;^6. enclosing Q. By taking dS sufficient!} small, we may regaid the area asperfectly plane, and the charge on the area will be crdS. The electricity onthe remainder of the conductor will exert forces of attraction or repulsion onthe charge adS, and these forces will shew themselves as a…
