The shortest distance between the straight lines `(x-6)/(1)=(2-y)/(2)=(z-2)/(2)" and "(x+4)/(3)=(y)/(-2)=(1-z)/(2)` isA. 9B. `(25)/(3)`C. `(16)/(3)`D. 4

Answer» Correct Answer - B
Given lines can be rewritten as ` (x -6)/(1) = (y-2)/(-2) = (Z-2)/(2) and (x+4)/(3) =(y)/(-2) =(z-1)/(-2)`
Here ,`" "x_(1) = 6, y_(1) = 2 , z_(1) =2 `
` x_(2) = - 4 , y_(2) 0 , z_(2) = 1`
`a_(1)=1, b_(1) = - 2 , c_(1) = 2`
and `" "a_(2) = 3,b_(2) = - 2 2,c_(2) = -2`
