MathematicsHard249×since 2002Q2610Let P be the plane passing through the points (5,3,0),(13,3,−2)(5,3,0),(13,3,-2)(5,3,0),(13,3,−2) and (1,6,2)(1,6,2)(1,6,2). For α∈N\alpha \in \mathbb{N}α∈N, if the distances of the points A(3,4,α)\mathrm{A}(3,4, \alpha)A(3,4,α) and B(2,α,a)\mathrm{B}(2, \alpha, a)B(2,α,a) from the plane P are 2 and 3 respectively, then the positive value of a is :A6B4C5D3Check answerSkip
