हिन्दीFor the three-dimensional vector \( \mathbf{A} \) resolved into rectangular components in the figure, if \( A_x = 2\text{ units} \), \( A_y = 3\text{ units} \), and \( A_z = 6\text{ units} \), what is the magnitude of vector \( \mathbf{A} \)?
Correct answer · Option 3
\( 7\text{ units} \)
Explanation
In 3D resolution, \( |\mathbf{A}| = \sqrt{A_x^2 + A_y^2 + A_z^2} = \sqrt{2^2 + 3^2 + 6^2} = \sqrt{4 + 9 + 36} = \sqrt{49} = 7\text{ units} \).
