Flux = E ⋅ A. E is electric field vector & A is area vector. Here, angle between E & A is 90°. Find flux.
- ϕ = q / ε₀
- ϕ = E ⋅ A
- ϕ = 0
- ϕ = q / 2ε₀
Correct answer: ϕ = 0
Solution
The electric flux is given by ϕ = E ⋅ A = EA cosθ. Since the angle between E and A is 90°, cos90° = 0, so the flux is 0.
