NCERT Exercise 1.14 - Electric Charges and Fields
Question: Consider a uniform electric field E = 3 × 10³ î N/C. (a) What is the flux of this field through a square of 10 cm on a side whose plane is parallel to the yz-plane? (b) What is the flux through the same square if the normal to its plane makes a 60° angle with the x-axis?
Answer: (a) Electric flux = **30 N·m²/C** (when plane is parallel to yz-plane, normal is parallel to E). (b) Electric flux = **15 N·m²/C** (when normal makes 60° with E field direction).
