Let a vector \overrightarrow{a}, has magnitude 9. Let a vector \overrightarrow{b} be such that for every (x, y) \in R \times R-\{(0,0)\}, the vector (x \overrightarrow{a}+y \overrightarrow{b}) is perpendicular to the vector (6 y \overrightarrow{a}-18 x \overrightarrow{b}). Then the value of |\overrightarrow{a} \times \overrightarrow{b}| is equal to: [28-Jul-2022-Shift-1]
