Answer:
B). An unbalanced force is acting on the brick.
Explanation:
Here as we can see the given figure there are two forces acting on the block
1. [tex]F_1 = 7,205 N[/tex] Upwards
2. [tex]F_2 = 7,210 N[/tex] Downwards
so here as we can see that force downwards is more in magnitude while upward force is less.
So here since downward force is more so the box will accelerate downwards and net force is given as
[tex]F_{net} = F_2 - F_1[/tex]
[tex]F_{net} = 7210 - 7205 = 5 N[/tex]
so here net force on this box is 5 N downwards and since there is unbalanced force on the box so box can not remains at rest.
