hello everyone welcome to lido learning i'm good free your science tutor today's question is a boy pushes a wall with a force of 10 newton towards the east what force is exerted by the wall on the boy so in this question you have to tell that what was the force how much force was exerted by the wall on the boy so this question we will first study about the newton's third law of motion newton's third law of motion explains that for every action there is equal and opposite reaction so in this question if the wall was pushed by a boy with 10 newton force then in opposite of this action the wall will also push the boy with the 10 newton force but in the opposite direction that is the force was in each direction so its reaction will be in the west direction okay for more such videos please subscribe leader learning and for any doubts drop a comment thank you
