Solution
The question seems to be incomplete as it does not provide a diagram or further information about the scenario. However, if we assume a typical physics problem where two identical masses are connected by a string over a pulley (also known as an Atwood machine), then the system will be in equilibrium if there are no external forces.
If one mass is slightly perturbed, it will start to accelerate. The acceleration will not be equal to g (the acceleration due to gravity) because both masses are identical and the tension in the string provides an additional force.
The acceleration of the system can be calculated using Newton's second law (F=ma). The net force on the system is the difference in the weight of the two masses (which is zero since the masses are identical) minus the tension in the string. This net force equals the mass of the system times its acceleration.
Since the tension in the string is not zero, the acceleration of the system will be less than g. Therefore, the correct answer is "with an acceleration less than g."
