Question 1 The electric field in a region of space can be expressed by (425 +1.34103 +817) N/C. If a circle of diameter 5.00 cm is placed in the xz-plane of this region, what will be the electric flux through the circle? 3.19 N m/C 2.63 N m/c 0.834 N m/C 1.60 N m/C Question 2 In the figure above, the negative charge has a magnitude of 27.0 nC (and lies inside the doughnut shape) and the positive charge has a magnitude of 69.0 nC. What is the flux through the doughnut surface? -7.80x103 Nm/C -3.05103 Nm/c 3.05103 Nm/C 7.8010 Nm/C Question 3 Neutral Conducting Hollow Cylinder Charged Conducting Wire E, 2a 3a A very long charged conducting wire, of radius a = 13.0 cm, is enclosed by a concentric, conducting neutral hollow cylinder, as shown in the diagram above. If the electric field is E, = 1.10104 N/C at b = 19.0 cm from the center of the wire and in the direction shown, what is the linear charge density -1.16x107 C/m -1.5910-7 C/m O -9.4810-8 C/m O -7.9510-8 C/m of the wire?
