Question 1 The electric field in a region of space can be expressed by (3957 + 1.09x103j + 788 k) N/C. If a circle of diameter 25.0 cm is placed in the xz-plane of this region, what will be the electric flux through the circle? 68.8 N m2/C 38.7 N m2/c 19.4 N m2/c 53.5 N m2/C Question 2 The flux through a hexagonal prism is -1.23x103 Nm2/C. What is the charge inside the hexagonal prism? O -31.5 C O -1.09x10-8 c O -1.12x103 c O 1.23x103 c Question 3 Neutral Conducting Charged Hollow Cylinder Conducting Wire E, 2a 3a b A very long charged conducting wire, of radius a = 7.00 cm, is enclosed by a concentric, conducting neutral hollow cylinder, as shown in the diagram above. If the electric field is E1 = 1.20x104 N/C at b = 10.0 cm from the center of the wire and in the direction shown, what is the linear charge density 12 of the inner surface of the hollow cylinder? O 6.67x10-8 C/m 9.34x10 8 C/m O 4.67x10-8 c/m O 2.93x10-8 c/m
