Vectors Question 206
Question: A vector having magnitude 30 unit makes equal angles with each of X, Y and Z axes. The components of vector along each of X, Y and Z axes are
Options:
A) $ 10\sqrt{3} $ unit
B) $ \frac{10}{\sqrt{3}} $ unit
C) $ 15\sqrt{3} $ unit
D) 10 unit
Correct Answer: A [a] $ A _{x}=A _{y}=A _{z} $ Now, $ A,=,\sqrt{A_x^{2}+,A_y^{2},A_z^{2}}=,\sqrt{3},A _{x} $ Therefore $ $ A _{x}=,\frac{A}{\sqrt{3}},=\frac{30}{\sqrt{3}},=,10\sqrt{3} $
