Electric Flux Through a Uniform Electric Field

[musicman05]

You have a uniform electric field described by the vector (4 i + 2 j + 13 k)N/C and a flat surface describe by the vector (5 i + 9 j - 2 k)m2. What is the electric flux through this surface?

You have a uniform electric field described by the vector (4 i + 2 j + 13 k)N/C and a flat surface describe by the vector (5 i + 9 j - 2 k)m2. What is the electric flux through this surface?

The vector describing a surface is usually normal to the surface. What is the definition of the flux of a vector field?
