Need solution for RD Sharma maths class 12 chapter 27 Straight Line in Space exercise Multiple choice question 15
Answer: Correct answer is A.
Hint: y-axis lies on xy plane and y2
Given: The equation of y-axis in space.
Solution: As -axis lies on xy plane and y2
So, its distance from xy and yz plane is 0.
∴ By basic definition of 3-D coordinate we can say that x-coordinate and z-coordinate =0
∴ Any point on y-axis has x and z-coordinate =0
∴x=0 and z=0 Can be considered as the equation of y-axis.
Hence, the correct option is (A)
