Question

whty do we sprinkle powder on the surface of carom board​

Answer 1

Answer:

Sprinkling of powder makes the surface of the board smoother than before due to comparatively less inter-locking between irregularities of the surfaces. The coins face comparatively less resistance. Thus, we can conclude that the friction has been reduced.

Answer 2

$\huge\underline\mathtt{Answer}$

The carrom board may sometimes be very rough. Sprinkling powder on a microscopic level, the powder particles offer rolling friction to the striker because of which the striker can be used for smooth and fast play.
