Three-Dimensional-Geometry Question 420
Question: The shortest distance of the point (a, b, c) from the x-axis is
[MP PET 1999; DCE 1999]
Options:
A) $ \sqrt{(a^{2}+b^{2})} $
B) $ \sqrt{(b^{2}+c^{2})} $
C) $ \sqrt{(c^{2}+a^{2})} $
D) $ \sqrt{(a^{2}+b^{2}+c^{2})} $
Show Answer
Answer:
Correct Answer: B
Solution:
Distance from x-axis = $ \sqrt{y^{2}+z^{2}}=\sqrt{(b^{2}+c^{2})} $ .
