Problem

Blocks A (

2.0\,\text{kg}

) and B (

3.0\,\text{kg}

) are connected by a light rope and rest on a frictionless horizontal surface. A constant horizontal force of

15\,\text{N}

pulls block A to the right so that the two blocks accelerate together. What is the magnitude of the tension in the rope? a)

7.5\,\text{N}

9\,\text{N}

15\,\text{N}

6\,\text{N}
