suppose you are standing on your bathroom scales and observe its reading. now suppose you put you hand on top of a nearby counter and push down on it. how will the scale reading change?
a scale reading decreases
b scale reading does not change
c scale reading increases

Explanation:

When you push down on the counter, according to Newton's third - law, the counter exerts an upward reaction force on you. This reduces the normal force exerted by you on the scale, and the scale reading is equal to the normal force acting on it. So the scale reading decreases.

Answer:

A. Scale reading decreases
