MathematicsHard249×since 2002Q2431Let L be the line of intersection of planes r→.(i^−j^+2k^)=2\overrightarrow r .(\widehat i - \widehat j + 2\widehat k) = 2r.(i−j+2k)=2 and r→.(2i^+j^−k^)=2\overrightarrow r .(2\widehat i + \widehat j - \widehat k) = 2r.(2i+j−k)=2. If P(α,β,γ)P(\alpha ,\beta ,\gamma )P(α,β,γ) is the foot of perpendicular on L from the point (1, 2, 0), then the value of 35(α+β+γ)35(\alpha + \beta + \gamma )35(α+β+γ) is equal to :A101B119C143D134Check answerSkip
