A surface element `vec(ds) = 5 hat(i)` is placed in an electric field

1.	A surface element `vec(ds) = 5 hat(i)` is placed in an electric field `vec(E) = 4 hat(i) + 4 hat(j) + 4 hat(k)`. What is the electric flux emanting from the surface ?
Answer» Here, `vec(ds) = 5 hat(i) , vec(E) = 4 hat(i) + 4 hat(j) + 4 hat(k)` Electric flux, `phi = vec(E). vec(ds) = (4 hat(i) + 4 hat(j) + 4 hat(k))* 5 hat(i)` `phi = 20 units`
