3) may move the object and also cause a change in its shape.
4) do not move the object but may cause a change in its shape.​

Answer 1

Answer:

If two forces are applied on an object in opposite directions, then the net force acting on the object is the difference between the two forces. Thus, in the given case, the net force acting on the object is A - B.
