question 19

Multiple Choice

A uniform electric field with a magnitude of $6 \times 10 ^ { 6 } \mathrm {~N} / \mathrm { C }$ i is directed along the $+ x$ -axis. A cube having edges of length $0.1 \mathrm {~m}$ is oriented as shown in the figure. What is the electric flux passing through the shaded face of the cube?

• A) \(600 \times 10^4 \mathrm { Nm } ^ { 2 } / \mathrm { C }\)
• B) \(6 \times 10 ^ { 4 } \mathrm { Nm } ^ { 2 } / \mathrm { C }\)
• C) \(6000 \times 10 ^ { 4 } \mathrm { Nm } ^ { 2 } / \mathrm { C }\)
• D) \(0.6 \times 10 ^ { 4 } \mathrm { Nm } ^ { 2 } / \mathrm { C }\)
• E) \(60 \times 10 ^ { 4 } \mathrm { Nm } ^ { 2 } / \mathrm { C }\)
