Solution
The correct option is C 2
Answer:− B Pushing, hitting and pulling of objects are all ways of bringing objects in motion. This friction force arises between two surfaces in contact. No motion of the wood (in fig) will take place if it is at rest and equal forces in both direction are applied, but no net force is needed to sustain the uniform motion of the marble.
By newtons third law: For every action, there is an equal and opposite reaction. So two forces come into picturure for action.
