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 \( A B C \) satisfies the relation \( \frac{1}{x^{2}}+\frac{1}{y^{2}}+\frac{1}{z^{2}}=k \), then the value of \( k \) is the value of \( k \) ishttps://bit.ly/YTAI_PWAP https://www.pw.live
