Question

A 5kg block rest on the horizontal surface .which of the following is incorrect ? ( g=10m/s^2)​

Answer 1

Answer:

Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object

Weight, W=mg=5×10=50N

Hence, The normal force on the block equals its weight because of Newton's third law equal to 50 N
