Q. Three forces $\overline{F_1}, \overline{F_2} and \overline{F_3}$   act on a body in equilibrium. There is no other force on the body. If  F₁  is removed , the  acceleration of the body is a. The acceleration of the body if F₂ is removed is:
(1) $\frac{\left|\overline{F_1}\right|}{\left|\overline{F_2}\right|}a$                         (2) $\frac{\left|\overline{F_2}\right|}{\left|\overline{F_1}\right|}a$
(3) $\frac{\left|\overline{F_2}\right|+\left|\overline{F_3}\right|}{\left|\overline{F_1}\right|+\left|\overline{F_3}\right|}a$              (4) $\frac{\left|\overline{F_1}\right|+\left|\overline{F_3}\right|}{\left|\overline{F_2}\right|+\left|\overline{F_3}\right|}a$
