Answer:
D
Solution:

Given:

E = 600 ĵ N/C

Plate dimensions = 4 cm × 6 cm = 0.04 m × 0.06 m

Area A = 0.0024 m²

 

Plate makes 37° with the electric field.

Angle between field and area vector (normal):

θ = 90° – 37° = 53°

 

Flux:

Φ = E A cosθ

= 600 × 0.0024 × cos 53°

= 1.44 × 0.6018

≈ 0.864 N·m²/C

 

Answer: (4*) 0.864 N·m²/C
