Q:- Two systems of rectangular axes have the same origin. If a plane cuts them at distances a,b,c and a1,b1,c1 from the origin, then
A.(1/a^2)+(1/b^2)+(1/c^2)=(1/a1^2)+(1/b1^2)+(1/c1^2)
B. (1/a^2)-(1/b^2)+(1/c^2)=(1/a1^2)-(1/b1^2)+(1/c1^2)
C. (a^2)+(b^2)+(c^2)=(a1^2)+(b1^2)+(c1^2)
D.(a^2)-(b^2)+(c^2)=(a1^2)-(b1^2)+(c1^2)
