Answer: The object is accelerating in the downward direction.
Explanation: In the given block diagram, there are 4 forces acting on the object.
- The force which is acting on the right side of the object gets cancelled out by the force acting on the left side. Net force on the horizontal line = (100N - 100N) = 0 N.
- The force acting in the downward direction is more than the force acting on the upward direction. Net force on the vertical line = (720N - 600N) = 120N
We know that,
The object moves in the direction of the net force and here, the net force is acting in the downward direction.
And, F = ma
Acceleration will be in the direction of the force only. Hence, the object will be accelerating in the downward direction.
