Question

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

• A. It increases 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.
