A variable plane at a distance of 1 unit from the origin cuts the co-ordinate axes at A, B and C. If the centroid D (x, y, z) of triangle ABC satisfies the relation
\(\frac{1}{x^{2}}+\frac{1}{y^{2}}+\frac{1}{z^{2}}=k\), then the value of k is
\(\frac{1}{x^{2}}+\frac{1}{y^{2}}+\frac{1}{z^{2}}=k\), then the value of k is
- 9
- 1
- 3
