Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Define the vectors \vec{A}\ and \vec{B}\ as shown in the images. Assume \vec{A} = |\vec{A}|\hat{i} and \vec{B} = |\vec{B}|\hat{j}.
Step 2: Calculate the resultant vector: \vec{R} = \vec{A} + \vec{B}.
This results in \vec{R} = |\vec{A}|\hat{i} + |\vec{B}|\hat{j}.
Step 3: Calculate the magnitude of the resultant vector: |\vec{R}| = \sqrt{|\vec{A}|^2 + |\vec{B}|^2}.
Step 4: Based on the calculations, it can be established that the value of |
+
| is indeed |\vec{A}| |\vec{B}|.
Step 2: Calculate the resultant vector: \vec{R} = \vec{A} + \vec{B}.
This results in \vec{R} = |\vec{A}|\hat{i} + |\vec{B}|\hat{j}.
Step 3: Calculate the magnitude of the resultant vector: |\vec{R}| = \sqrt{|\vec{A}|^2 + |\vec{B}|^2}.
Step 4: Based on the calculations, it can be established that the value of |
+
| is indeed |\vec{A}| |\vec{B}|.
