IOM 2020, Блиц — Задача 43

The Blitz-contest of IOM-2020

Условие

A neutral sub-atomic particle at rest in a magnetic field of flux density B=10−5B = 10^{-5} T. It spontaneously decays into two particles of mass mm each. One of the particles has a negative charge q=−1μq = -1\muC. The particles move with velocities perpendicular to the magnetic field. After what time will the particles collide if m=2⋅10−11m = 2 \cdot 10^{-11} kg?

The answer should be given in the SI units unless otherwise stated. If the numerical result turns out to be an integer, it should be given as the answer. Otherwise round the result to the first decimal.
