Two Identical Tiny Balls of Highly Compressed Matter Are $2.00 \mathrm {~cm} / \mathrm { s } ^ { 2 }$

Short Answer

Two identical tiny balls of highly compressed matter are 1.50 m apart. When released in an orbiting space station, they accelerate toward each other at $2.00 \mathrm {~cm} / \mathrm { s } ^ { 2 }$
What is the mass of each of them? $\left( G = 6.67 \times 10 ^ { - 11 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { kg } ^ { 2 } \right)$
