Problem

Two forces act on a body:

\mathbf P = 4\,\hat i - 3\,\hat j\,\text{N}

and

\mathbf Q = -6\,\hat i + 5\,\hat j\,\text{N}

. A third force

\mathbf R

keeps the body in equilibrium. If

\mathbf R

makes an angle of

45^{\circ}

below the positive x-axis, find the magnitude of

\mathbf R

. a)

3.0\,\text{N}

b)

2\sqrt{2}\,\text{N}

c)

4.0\,\text{N}

d)

2\,\text{N}
