Question

Assertion (A) : A line in space cannot be drawn perpendicular to x, y and z axes simultaneously. Reason (R) : For any line making angles, α, β, γ with the positive directions of x, y and z axes respectively, cos² α + cos² β + cos² γ = 1.

Find the values of λ, for which the distance of point (2, 1, λ) from plane 3x + 5y + 4z = 11 is 2√2 units.
