If you exert a force F of an object, the force which the object exerts on you will

O Depend on whether or not the object is moving.
Depend on whether or not you are moving.
Depend on the objects mass.
• Always be -F.
• Depend on your mass.

The force which the object exerts on you will always be equal in magnitude but opposite in direction to the force you exert on the object. This is known as Newton's third law of motion. So, the correct answer is:

• Always be -F.
