JEE MainMathematics3D GeometryMCQ+4 / −1
The foot of perpendicular of the point (2, 0, 5) on the line x+12=y−15=z+1−1{{x + 1} \over 2} = {{y - 1} \over 5} = {{z + 1} \over { - 1}}2x+1​=5y−1​=−1z+1​ is (α,β,γ\alpha,\beta,\gammaα,β,γ). Then, which of the following is NOT correct?
  1. A
    αβ=−8\frac{\alpha}{\beta}=-8βα​=−8
  2. B
    αβγ=415\frac{\alpha \beta}{\gamma}=\frac{4}{15}γαβ​=154​
  3. C
    βγ=−5\frac{\beta}{\gamma}=-5γβ​=−5
  4. D
    γα=58\frac{\gamma}{\alpha}=\frac{5}{8}αγ​=85​
