IOM 2021, Блиц — Задача 64

The Blitz-contest of IOM-2021

Условие

Five small spheres (whose masses are $2.00$ kg, $2.05$ kg, $2.10$ kg, $2.15$ kg and $2.20$ kg) hang from a horizontal rigid tube. Each mass hangs from an identical fishing line that can withhold a maximum tension of $22.2$ N. When this device is placed inside an elevator that accelerates upwards, the only threads that do not break are the ones holding the $2.00$ kg and $2.05$ kg masses. What could be the maximum acceleration of the elevator? Suppose $g = 9.80$ m/s$^2$. Give answer in m/s$^2$, rounded to the second decimal.
