Answer:
150 N to the right
Explanation:
Force acting on the box applied by Sally, [tex]F_1=100\ N[/tex] (right side)
Force acting on the box applied by Ann, [tex]F_2=50\ N[/tex] (right side)
It is clear that the two forces are acting on same direction. Let right side is positive direction. So,
[tex]F=F_1+F_2[/tex]
[tex]F=100+50[/tex]
F = 150 N
The direction of the box is towards right side. So, the correct option is (a).
