Problem

Three forces act successively on a particle: 1.

\mathbf{P}

of magnitude

4\,\text{N}

toward the east, 2.

\mathbf{Q}

of magnitude

3\,\text{N}

directed

45^{\circ}

north of east, 3.

\mathbf{R}

of magnitude

2\,\text{N}

toward the south. Find the magnitude of the resultant force on the particle. a)

7.1\,\text{N}

6.1\,\text{N}

5.5\,\text{N}

6.5\,\text{N}
