Q1 FREE PREVIEW

Direction ratios of a vector parallel to line \(\frac{x-1}{2}=-y=\frac{2 z+1}{6}\) are :

a

\(2,-1,6\)

b

\(2,1,6\)

c

\(2,1,3\)

d

\(2,-1,3\)

✓ Correct answer: d)

\(2,-1,3\)

Explanation

Given equation of the line is

\( \frac{x-1}{2}=-y=\frac{2 z+1}{6} \)
\( \Rightarrow \frac{x-1}{2}=\frac{y-0}{-1}=\frac{2\left(z+\frac{1}{2}\right)}{6} \)
\( \Rightarrow \frac{x-1}{2}=\frac{y-0}{-1}=\frac{z+\frac{1}{2}}{3}\)

The direction ratios of the line are \((2,-1,3)\).
