The Assertion (A) is false but Reason (R) is true.

Explanation:

  • Friction is a force that acts opposite to the direction of motion of the body since it is a resistive force.
  • There are two types of friction: Static friction and Kinetic friction.
  • The force that emerges during friction is known as frictional force.
  • Static friction works when two surfaces are not moving relative to each other, while kinetic friction acts when the two objects are in motion.
  • Generally, friction is caused due to irregularities in the body's surface.
  • Therefore, polishing a surface reduces the friction of the surface.​
  • If we polish it beyond a certain limit, then it may increase the frictional force of the body.
