Query: Tidal disruption of NEAs - a case of P\v{r}\'ibram   This work studies the dynamical evolution of a possible meteor stream along
the orbit of the P\v{r}\'{i}bram meteorite, which originated in the tidal
disruption of the putative rubble-pile-like parent body during a close approach
to the Earth. We assumed the disruption at the time when the ascending or
descending node of the parent orbit was close to the Earth's orbit. In the last
5000 years, the P\v{r}\'{i}bram orbit has crossed the Earth orbit twice. It
happened about 4200 years and 3300 years ago. In both cases, we modeled the
release of particles from the simplified model of rotating asteroid, and traced
their individual orbital evolution to the current date. It takes several
hundred years to spread released meteoroids along the entire orbit of the
parent body. Even today, the stream would be relatively narrow.
  Considering a model parent body with physical parameters of the asteroid
Itokawa, the complete disintegration of the object produced 3.8$\times10^{11}$
meteoroid particles with diameter $\geq$ 1\,cm. The meteor activity observed
from the Earth is revealed and justification of follow-up observation during
suggested activity of the shower in the first two weeks of April is discussed.
  The Earth's tidal forces would disintegrate a fraction of NEA population into
smaller objects. We evaluate the upper limit of mass of disintegrated asteroids
within the mean NEA lifetime and the contribution of disrupted matter to the
size distribution of the NEA.
