a) 0.054 N m²/C

b) 0

c) 0.0467 N m²/C

Explanation:

a) Electric flux = Φ = E A cos θ

E = Electric field = 27 N/C

Area = A = 0.05*0.04 = 0.002 m²

Angle = θ = 0, since they are parallel.

Φ = Electric flux = (27) (0.002) (cos 0) = 0.054 N m²/C

b) When θ = 90°, perpendicular

Ф = Electric flux = (27) (0.002) (cos 90) = 0

c) θ = 30 degrees,

Φ = Electric flux = (27) (0.002) (cos 30) = 0.0467 N m²/C
