Consider a uniform electric field `E = 3xx10^(3) hat(i) 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 ?

B. `20 N C^(-1) m^(2)`
C. `30 N C^(-1) m^(2)`
D. `40 N C^(-1) m^(2)`
