In the above figure, the arrows indicate the direction of forces F1 and F2, the magnitudes of the respective force are given above the arrows, towards which direction will the block move?
The block will move towards the direction of F1 force.
Since forces are unequal, they are unbalanced. The unbalanced force causes motion. The direction of motion is along the direction of the greater force. In this case, F1 is the greater force, so the body will move along F1 force.
