Question

If a square coil is making an angle $60^{\circ }$ with electric field $E$ according to figure the electric flux passing through the square coil is (the side of square is $4\, cm$):

• A. 853 E
• B. 8 E
• C. 16 E
• D. none of these

Answer 1

Answer: (B)

8 E

Answer 2

The flux passing through the coil $\Delta \phi=\vec{ E } \cdot \Delta \vec{ S }$ $=E \Delta S \cos 60^{\circ}$ $=E \times(4 \times 4) \times \frac{1}{2}$ $=8\, E$
