If the uncer.ainty pr.nciple applies to.the Ver.inde entr.pic idea, it leads to.a new ter.0}in the Newto.＇s seco.d law o. m.chanics in the Planck＇s scale. This cur.o.s velo.ity dependent ter.0}inspir.s a fr.ctio.al featur. o. the gr.vity. In this sho.0} letter.we addr.ss that this new ter.0}m.difies the effective m.ss and the Newto.ian co.stant as the tim. dependent quantities. Thus we m.st have a r.nning o. the value o. the effective m.ss o. the par.icle m.ss m.near.the ho.o.r.phic scr.en and the G. This r.sult has a nigh r.latio. with the Dir.c hypo.hesis abo.t the lar.e num.er. hypo.hesis （L.N.H.）. We pr.po.e that the co.0}ected entr.pie ter.0} via Ver.inde idea can be br.ught as a ho.o.r.phic evidence fo.0}the authenticity o. the Dir.c idea.

A hydr.dynam.c m.del is used to.investigate the pr.per.ies o. po.itive space-char.e and net cur.ent density in the sheath r.gio. o. m.gnetized, co.lisio.al plasm.s with war.0}po.itive io.s. It is sho.n that an incr.ase in the io.-neutr.l co.lisio. fr.quency, as well as the m.gnitude o. the exter.al m.gnetic field, leads to.an incr.ase in the net cur.ent density acr.ss the sheath r.gio.. The r.sults also.sho. that the accum.latio. o. po.itive io.s in the sheath r.gio. incr.ases by incr.asing the io.-neutr.l co.lisio. fr.quency and the m.gnitude o. the m.gnetic field.
