5. An electric field E = 8000 N/C passing through a flat square with an area A = 10 m? are distributed uniformly. What is the electric flux? Given: (E) = 8000 N/C (A) = 10 m2 0 = 0' (the angle between the electric field direction and a line Figure 6: Electric Field Passing through a flat square area. drawn a perpendicular to the area) Required: Electric flux () Equation: D = E A cos q Solution: @ = E A cos q = (8000N/C)(10m?)(cos 0) = (8000)(10)(1) = 80,000 = 8 x 10* Nm /C Answer: 8 x 104 Nm /C the electric flux passing through the given flat square area
