Question

How is friction between coins and carrom board affected when some powder is sprinkled on the carrom board?

• A. It increases a little.
• B. It increases to a large extent.
• C. It doesn't change.
• D. It decreases.

Answer 1

The correct option is D

It decreases.

Sprinkling of powder makes the surface of carrom board smoother. This decreases interlocking between the surfaces and results in formation of fewer bonds between them. Thus, frictional force reduces between the coins and the carrom board.
