gauss law

The Attempt at a Solution

I got D.

Integral ( E dot da) = q(enc)/ e0
E is constant so iit can come out and the angle between them is zero (cos(0)=1

|E| integral (da)

which gives me
|E| a

where a=4 pi r^2

c *(r/e0) * 4 pi r^2

q(enc)= c*4*pi*r^3

Looks good to me.
 
To me the problem statement looks rather empty !

Oh wow! It disappeared. When I first looked at this there was a photograph of a problem. I wonder what happened?

It would help greatly if those helping with Homework would use the "Reply" feature. In particular, use The "Reply" feature to make sure that there is a readily available copy of the Original Post.
 
Consider that a task for the forum software. A historian or something. All this "full post reply" stuff just fills my screens with mostly superfluous copies.
