FIGURE 6-5 -Two masses, m₁ and m₂, are connected to each other as shown in Figure 6-5. Mass m₁ slides without friction on the table surface. Both masses have acceleration of magnitude a as shown. How does the tension in the string compare to the weight, m₂g, of mass m₂? A) The tension is equal to m₂g. B) The tension is larger than m₂g. C) The tension is smaller than m₂g. D) It depends on m₁ being smaller than m₂. E) It depends on m₁ being larger than m₂.

Since there is no friction on m₁, the tension in the string is only there to balance the weight of m₂. Therefore, since both masses have the same acceleration, the tension in the string must be smaller than m₂g in order to balance the system.
