Problem

Three carts of masses

m_1 = 1.0\,\text{kg}

m_2 = 2.0\,\text{kg}

, and

m_3 = 3.0\,\text{kg}

are connected in a line by two light strings on a frictionless track. A constant horizontal force of

12\,\text{N}

pulls on the

3.0\,\text{kg}

cart toward the right. What is the magnitude of the tension

T

in the string between the

1.0\,\text{kg}

and

2.0\,\text{kg}

carts? a)

6.0\,\text{N}

12\,\text{N}

2.0\,\text{N}

4.0\,\text{N}
