JEE Main 2025 Physics question
The electric field in a region is given by N/C. The flux of the field through a rectangular surface parallel to x-z plane is 6.0 Nm²C⁻¹. The area of the surface is cm².
Answer: 15
Solution
For surface parallel to xz-plane, only the j-component contributes: 6 = A×4×10³, giving A=15 cm².
