Which of the following statements are correct ?
(A) Direction ratios of the line $\frac{x-1}{2}=\frac{y+2}{3}=\frac{z-3}{4}$ are 2, 3, 4
(B) Direction ratio of the line $\frac{x-1}{2}=\frac{2-y}{7}=\frac{2z-1}{6}$ are 2, -7, 3
(C) Direction cosines of x axis are 0, 1, 0
(D) Direction ratios of the line joining the point (1, 2, -3) and (4, 5, 6) are 1, 1, 3.
(E) Direction cosines of a line which makes equal angles with the coordinates axes are $\frac{1}{3}, \frac{-1}{3}, \frac{1}{3}$
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A), (B), (D) Only
for (C) direction ratio of x axis is (1, 0, 0) Not (0, 1, 0)
(E) Direction cosines of lines which makes equal angles with axis is $\frac{1}{\sqrt{3}}, \frac{1}{\sqrt{3}}, \frac{1}{\sqrt{3}}$ Not $\frac{1}{3}, \frac{-1}{3}, \frac{1}{3}$
