Two system of rectangular axes have the same
origin. If the plane cuts the axes at dostances
a, b, c to the first system and `a', b', c'` to the
second system of rectangular axes from the origin
then

Options

A. `1/(a^(2))+1/(b^(2))+1/(c^(2)) =1/((a')^(2))+1/((b')^(2))+1/((c')^(2))`
B. `1/(a^(2))+1/(b^(2))+1/(c^(2)) +1/((a')^(2))+1/((b')^(2))+1/((c')^(2))=0`
C. `1/a =1/(a'), 1/b=1/(b'), 1/c =1/(c')`
D. `1/a =-1/(a'), 1/b=-1/(b'), 1/c =-1/(c')`

Answer

A
