Question 49 NECO • 2025 • PHYSICS • objective

Two vectors are given in component form: \(\mathbf{A}=5\,\hat{i}+2\,\hat{j}\) and \(\mathbf{B}=-3\,\hat{i}+4\,\hat{j}\). Find the magnitude of the resultant vector \(\mathbf{R}=\mathbf{A}+\mathbf{B}\) and the angle \(\theta\) it makes with the positive \(x\)-axis (express \(\theta\) to one decimal place).

Answer Options

A. Magnitude \\(= 7.21\\) (units); direction \\(= 78.0^{\\circ}\\) from the +x‑axis
B. Magnitude \\(= 6.32\\) (units); direction \\(= 45.0^{\\circ}\\) from the +x‑axis
Correct Answer C. Magnitude \(= 6.32\) (units); direction \(= 71.6^{\circ}\) from the +x‑axis
D. Magnitude \\(= 5.00\\) (units); direction \\(= 63.4^{\\circ}\\) from the +x‑axis
Correct Answer
C
Correct Option:
Magnitude \(= 6.32\) (units); direction \(= 71.6^{\circ}\) from the +x‑axis
