question

Two point charges of 30nC30 \mathrm{nC} and −40nC-40 \mathrm{nC} are held fixed on an xx axis, at the origin and at $x=72 \mathrm{~cm}$, respectively. A particle with a charge of 42μC42 \mu \mathrm{C} is released from rest at $x=28 \mathrm{~cm}$. If the initial acceleration of the particle has a magnitude of $100 \mathrm{~km} / \mathrm{s}^2$, what is the particle's mass?
