Addition & Subtraction of Vectors

Two forces having magnitude $A$ and $\frac{A}{2}$ are perpendicular to each other. The magnitude of their resultant is:

Show answer and solution

Answer: (c)

For perpendicular vectors $R = \sqrt{A^2 + B^2}$ .
$R = \sqrt{A^2 + \frac{A^2}{4}} = \frac{\sqrt{5}A}{2}$
So the answer is (c).
