The motion of a boat moving away from the shore is an example of :
- Newton's first law
- Newton's second law
- Newton's third law
- not related with Newton's law
Answer
Newton's third law
Reason — To move a boat ahead in water, the boatman pushes (action) the water backwards with his oar and at the same time, the water exerts an equal and opposite force (reaction) in the forward direction on the boat due to which the boat moves ahead. Hence, it is an example of Newton's third law
