Given $\vec a=\hat i+2\hat j-3\hat k$, $\vec b=2\hat i-\hat j+\hat k$, and line $L$ has equation $\vec r\times\vec b=\vec a\times\vec b$.
If 'C' be the curve in the-y plane satisfying (where be the position vector of a variable point on the curve), then the minimum distance of line ' L ' from the centre of curve 'C' is-
Options:
Answer:
B
