as total mass decides the amount of gravity any body has; thousands of tons of space debries fall to earth each year,what would a 100 pound object weigh in 100 years 1,000 or10,000 years and what is the formula of gravity increase.

Assuming, for the sake of simplicity, constant density, the acceleration of gravity at the surface of a sphere is proportional to the cube root of the mass. The relative mass increase from infalling material is maybe on the order of 5 parts per billion per million years, so gravity increases by 1-(1 + 5E-9)^1/3, or about 1.7 parts per billion per million years.

Too insignificant to matter.
