Question

Problem 22.59 experiment the electric fold is measured for points at distances r from a uniform line of charg that has charge per unit length Aand length l, wherel>T In a second experiment the electric field measured for points at distances rfrom the center of a uniformly charged insuleting sphere that has volume charge density pand radiue R-8.30 mm, where r R. The results of the two the table below, but you aren't told which set of data appli to which Ir (cm) 100 200 250 E00 E50 400 E(10 N/C) Measurement B EC10 N/C) Part E which data set. A or B is for the unikom ine or charge and which setis for the uniormly charged sphere? select the correct answer and explanation Er constant for data set A and Era -constant for data sot B. Thus, data set Ais for line of charge and data set Bis for a unitommly charged sphere O Er constant for data set A and Er-constant fordata setB Thus, data set Aisfor uniformly chharged sphere and dste set Bis for a uniformline of clarge O constant for deta set Aand Br constant for dataset B Thus, data set A is for a uniformly charged sphere and dsta set Bis for a uniform line of charge. O Ba constant for data set A and Br-constant fordato set B Thus, data set Ais for a uniform line of charge and dato oot Bis for a uniformly charged sphere. Answers Give Up Correct Part F use the graph in part A to calculate A for the unromm line of charge. to two significant figures and include the appropriate units. o.15, Give Up Correct Part G use the graph in part D to calculate p for the uniformly charged insulating Rphere. Express your to two significant figures and include the appropriate units. 42.10 Submit My Answers Give Up incorrect Try Again: 3 attempts remaining

Explanation / Answer

Part G )

from graph

Er^2 = 55

we know that

Er^2 = charge density x volume x K

55 = charge density x volume of sphere x k

charge density = 2.55 x 10-3 C/m^3
