Identical isolated conducting spheres 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters (Fig. 21-22a). The electrostatic force acting on sphere 2 due to sphere 1 is F. Suppose now that a third identical sphere 3, having an insulating handle and initially neutral, is touched first to sphere 1 (Fig. 21-22b), then to sphere 2 (Fig. 21-22c), and finally removed (Fig. 21-22d). The electrostatic force that now acts on sphere 2 has magnitude F'. What is the ratio F'/F?

You can easily convert common units and measures electronically,
but you still should be able to use a conversion table, such as
those in Appendix D. Table 1-6 is part of a conversion table for a
system of volume measures once common in Spain; a volume of 1
fanega is equivalent to 55.501 dm^3 (cubic decimeters).To complete
the table, what numbers (to three significant figures) should be entered
in (a) the cahiz column, (b) the fanega column, (c) the cuartilla
column, and (d) the almude column, starting with the top
blank? Express 7.00 almudes in (e) medios, (f) cahizes, and (g) cubic
centimeters (cm^3).
