JEE Main 4 April 2024, Shift 2, Maths Q16

Question 16 of 90 in this shift, Maths question 16 of 30, Section A.

Let P be the point of intersection of the lines

\frac{x-2}{1}=\frac{y-4}{5}=\frac{z-2}{1}

and

\frac{x-3}{2}=\frac{y-2}{3}=\frac{z-3}{2}

. Then, the shortest distance of P from the line
