Chapter 3, Problem 47R

To determine

The effect on the reading of the scale if a person push down on a sink if the person is standing on the bathroom scale next to the sink.

Explanation of Solution

Introduction:

According to Newton’s third law, every action force there is always reaction force in opposite direction of action force.

When a person pushes on the sink in the descending direction, the sink pushes the person in the upward direction according to the Newton’s third law of motion. This will in general lift the person off the scale and diminishes the reading on the scale. On the off chance that the person pull upward on the sink, it will push the person descending and the scale reading will increase.

Conclusion:

The reading of the scale if a person push down on a sink if the person is standing on the bathroom scale next to the sink.
