Problem

Four horizontal forces act on a block resting on a frictionless table:

10\,\text{N}

right,

6\,\text{N}

left,

4\,\text{N}

left, and

3\,\text{N}

right. A fifth force is applied so that the block remains at rest. What should be the magnitude and direction of this fifth force? a)

7\,\text{N}

left b)

3\,\text{N}

right c)

3\,\text{N}

left d)

13\,\text{N}

left
