Final answer:
The question lacks sufficient detail to calculate the tension in string number 2, as it only provides the masses of two objects and no information on the system's setup or additional forces.
Step-by-step explanation:
To find the tension in string number 2, assuming it's an Atwood machine setup (which typically involves two masses connected by a string over a pulley), we would need to consider the entire system's acceleration and the individual forces on each mass. Unfortunately, the given data is not sufficient to solve the problem since we only have the masses of the two objects and no information about their configuration or the forces acting on them. Normally, Newton's second law would be used, which relates acceleration to force via the equation F = ma. However, without additional details on the system such as the presence of friction, the nature of the pulley, or any additional forces acting on the system, we cannot calculate the tension.
