A block of mass m1 slides on a frictionless tabletop. It is connected to a string that passes over a pulley and suspends a mass m². Suppose m1 and m² are both increased by a factor of 2. What will be the effect on the acceleration of the system?
1) The acceleration will remain the same
2) The acceleration will be halved
3) The acceleration will be doubled
4) The acceleration will be quadrupled
