Two vectors \(\mathbf{A}\) and \(\mathbf{B}\) have magnitudes \(|\mathbf{A}|=8\) units and \(|\mathbf{B}|=6\) units respectively, and the angle between them is \(60^{\circ}\). Find (a) the magnitude of the resultant vector \(\mathbf{R}=\mathbf{A}+\mathbf{B}\) and (b) the angle that \(\mathbf{R}\) makes with \(\mathbf{A}\).

Answer Options

Correct Answer A. Resultant magnitude = 2\sqrt{37}\ (≈12.2) units; direction ≈25.3^{\circ} above \mathbf{A}
B. Resultant magnitude = 2\sqrt{30}\ (≈10.95) units; direction ≈15^{\circ} above \mathbf{A}
C. Resultant magnitude = \sqrt{200}\ (≈14.1) units; direction ≈40^{\circ} above \mathbf{A}
D. Resultant magnitude = \sqrt{150}\ (≈12.2) units; direction ≈35^{\circ} above \mathbf{A}
Correct Answer
A
Correct Option:
