Consider the following two cases which involve the motion of an object
Case 1: An apple falling from a tree towards the ground.
Case 2: To move a loaded cart on the horizontal ground.

• A. Case 1: Involves pushing of the apple by earth's gravitational force
• B. Case 1: Involves pulling of apple by earth magnetic force
• C. Case 2: Involves loaded cart to be moved by pulling force only
• D. Case 2: Involves loaded cart to be moved by both pulling or pushing force

Answer 1

Answer: (D)

Case 2: Involves loaded cart to be moved by both pulling or pushing force

Force is an external agent (push or pull) which changes the state of motion or rest of an object.

Case 1: An apple falling from a tree towards the ground involves the pulling of the apple by the earth's gravitational force.

Case 2: A loaded cart on the horizontal ground can be moved by both pulling or pushing force.
