Two system of rectangular axes have the same origin. If a plane cuts them at distance `a, b, c and a', b', c'` from the origin, then:

Options

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

Answer

(c)
