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
[AIEEE 2002]
(a) \( F_{1} / m \)
(b) \( F_{2} F_{3} / m_{1} \)
(c) \( \left(F_{2}-F_{3}\right) / m \)
(d) \( F_{2} / m \)
