3m
Explanation:
If a girl is 5m away from a mirror, she needs to walk a further 3m to be 2m away from her image.
5m-3m = 2m
Statement :- We assume the orthagonal sequence
in Hilbert space, now
, the Fourier coefficients are given by:

Then Bessel's inequality give us:

Proof :- We assume the following equation is true

So that,
is projection of
onto the surface by the first
of the
. For any event, 
Now, by Pythagoras theorem:


Now, we can deduce that from the above equation that;

For
, we have

Hence, Proved
Answer:
Neutrally charged!!!!!!!!!!!!!!!!!!!!!
