Problem

Two forces, each of magnitude

5\,\text{N}

, act simultaneously on a particle. Which of the following ranges correctly gives the magnitude

R

of their resultant force as the angle

\theta

between them varies from

0^{\circ}

180^{\circ}

? a)

5\sqrt{2}\,\text{N}\;\le R \le\; 10\,\text{N}

5\,\text{N}\;\le R \le\; 10\,\text{N}

0\,\text{N}\;\le R \le\; 10\,\text{N}

0\,\text{N}\;\le R \le\; 5\,\text{N}
