Find the shortest distance between the lines whose vector equations are


Firstly, consider







So, we need to find the shortest distance between and .


Now, We know that


Shortest distance between two lines and is


…(i)


Here, and



Now,


…(ii)


Now,



……….(iii)


……….(iv)


Now,


……….(v)


Now, using (i), we have


The shortest distance between the two lines,
