Question

In which of the following examples is the plowing effect majorly seen?

• A. A pen lying on a wooden table.
• B. A block kept on a metallic table.
  
• C. A heavy object placed on a carpet.
  
• D. A book sliding over another book.
  

Answer 1

The correct option is C A heavy object placed on a carpet.


When surfaces are soft or can change their shape easily, they get deformed when they come in contact with another object.
In the case of carpet, when a heavy object is placed on it, the deformation of the shape of carpet is observed.
This effect of the surfaces sinking into one another is known as plowing effect.
Hence, the plowing effect is majorly seen when a heavy object is placed on a carpet.
