Question

Consider a uniform electric field E =3x10³ i N/C. What is the flux of this field through a square of 10 cm on a side whose plane is parallel to YZ plane.What is the flux through the same square if the normal to its plane makes a 60⁰ angle with the axis

Answer 1

Hello!

The Electric Flux through a surface is given as

Φ = EACosθ

here A = 10 X10 = 100 cm² = 0.01 m²

and E = 3 X 10³ N/C

(1) Here Φ = EA = 3 X 10³ X 0.01

(2) Here Φ = EA = 3 X 10³ X 0.01 X Cos60

Calculations can be performed accordingly to get the answers.
