In one experiment the electric field is measured for points at distances $$r$$ from a uniform line of charge that has charge per unit length $$?$$ and length $$l$$, where $$l?r$$. In a second experiment the electric field is measured for points at distances $$r$$ from the center of a uniformly charged insulating sphere that has volume charge density $$?$$ and radius $$R=6.50\mathrm{mm}$$, where $$r>R$$. The results of the two measurements are listed in the table below, but you aren't told which set of data applies to which experiment. Use the graph in part A to calculate $$?$$ for the uniform line of charge Express your answer to two significant figures and include the appropriate units. Use the graph in part D to calculate $$?$$ for the uniformly charged insulating sphere. Express your answer to two significant figures and include the appropriate units.
