Q. When a force $F$ acts on a body of mass $m$, the acceleration produced in the body is $a$. If three equal forces $F_{1} = F_{2} = F_{3} = F$ act on the same body as shown in figure, the acceleration produced is

A) $(\sqrt{2} - 1)a$
B) $(\sqrt{2} + 1)a$
C) $\sqrt{2}a$
D) $a$
Explanation

(a) Resultant acceleration $(a)_{R}$= $\sqrt{2}a - a$
[image:5_image161.emf]
$(a)_{R} = (\sqrt{2} - 1)a$
