SATHEE: Kinematics Question 582

Kinematics Question 582

Question: Vector $\vec{A}$ makes equal angle with x, y and z-axis. Value of it’s components in terms of magnitude of $\vec{A}$ will be

Options:

A) $\frac{\vec{A}}{\sqrt{3}}$

B) $\frac{\vec{A}}{\sqrt{2}}$

C) $\sqrt{3} \vec{A}$

D) $\frac{\sqrt{3}}{\vec{A}}$

Show Answer

Answer:

Correct Answer: A

Solution:

[a] Let the components of $\vec{A}$ make angles $α$ , $β$ and $γ$ with x, y and z-axis respectively then $α = β = γ$ and $c o s^{2} α + c o s^{2} β + c o s^{2} γ = 1$
