Attempt-> Equivalence implies a ball in norm 1 admits a ball in norm 2 and vice versa. For normed linear spaces, I know that B(x,r) = x + r*B(0,1).

So, a ball with respect to norm 1, B1(x,r), admits a ball in norm 2 with say radius 's'.

Using the normed linear space property, I can conclude that for a vector 'y' in V, if ||y||2 < s

then ||y||1 < r.

I don't know where I am going =(
