Sprinkling of powder on the carom board ______________ friction.

Open in App

Solution

Powder makes the surface smooth, and a smooth surface has less friction.
When the powder is sprinkled, the interlocking between the surfaces is reduced.
When the interlocking between the surfaces reduces, the frictional force also reduces.
Sprinkling of powder on the carom board decreases friction
Sprinkling of powder on the carom board reduces friction.
