Question

If thrust applied on a wooden block placed on a table is increased, frictional force opposing the motion of the block on the table __________.

• A. will decrease
• B. will increase
  
• C. first increases and then decreases
• D. remains the same
  

Answer 1

The correct option is B will increase


Friction increases with increase in thrust because when thrust increases, interlocking and adhesion also increases. Therefore, if thrust applied on a wooden block placed on a table is increased, friction will increase.
