When forces $${F_1},\,\,{F_2},\,\,{F_3}$$ are acting on a particle of mass $$m$$ such that $${F_2}$$ and $${F_3}$$ are mutually perpendicular, then the particle remains stationary. If the force $${F_1}$$ is now removed then the acceleration of the particle is
A
$${F_1}/m$$
B
$${F_2}{F_3}/m{F_1}$$
C
$$\left( {F{}_2 - {F_3}} \right)/m$$
D
$${F_2}/m$$
