Flux=

.  

S

=EScosθ           S is the area through which electric field lines crosses

When plane is parallel to Y-Z plane then  θ=0      here S = a X a = a^2         a= 5cm

Flux =ES=4×10

when plane makes angle 30 degree with X axis then perpendicular to plane makes angle 60 degree to X axis  

hence

θ=60
