Find the magnitude of the electric flux through the sheet?

A= L*W= 0.600m*.400.

E= 71 N/C

angle= 20 deg

phi = E*A*cos(20 deg)

I don't know where i am making my mistake?

#2a solid sphere with radius 0.460.m carries a net charge of 0.300nC. Find the magnitude of the electric field at a point 0.103 m outside the surface of the sphere?

A=4*pi*r^2= 4*pi*(0.460)^2

E=(1/4*pi*epsilon_0)*(q/r^2)= (1/(4*pi*epsilon_0))((.300*10^-9)/(0.103^2))PHI=E*Awhere is my mistake?
