Answer:
Equal and opposite.
Explanation:
We know newton's gave three laws of motion.
1. Every object will remain at rest or in uniform motion in a straight line until and unless an external force is not applied to change its motion.
2. The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
3. For every action their is an equal and opposite reaction and both the action and reaction are opposite in direction.
So, the answer is equal and opposite.
Hence, this is the required solution.
