If vector A makes an angle of $\theta$with respect to the x axis and A_xis given in a two-dimensional rectangular coordinate system, then |A| is equal to A_x times A) sin $\theta$. B) l/(sin $\theta$). C) tan$\theta$. D) l/(cos $\theta$).

Question

Quizplus · Accepted Answer

The magnitude of vector A, |A|, is related to its x-component, A_x, by the cosine of the angle $\theta$. Therefore, |A| = A_x / cos($\theta$).
