What would be the impact on friction if a powder is sprinkled on the surface of the carrom board?

Solution

If the powder is sprinkled on the carom board:
If a powder is sprinkled on the carrom board it will reduce the friction.
The surfaces of the carrom board as well as the carom coins are not smooth.
So there will be friction between the board and the coins, which will act as resistance to their relative motion.
Now, if we apply powder to the board it will make the surface smoother, resulting in the reduction of friction.
Hence, friction reduces if power is sprinkled on the surface of the carrom board.
