Question

Which of these surfaces offers the least friction-ice, wood or coir mat?​

Answer 1

Answer:

Ice surface offers the least friction.

Explanation:

Answer 2

Answer:

From the given questions, Ice which is least friction acting on it hence it is really slippery to walk on ice.  

Explanation:

• Ice is a form of water in solid phase. Hence there are no aberrations present on the surface of eyes and even if there are small inequalities there covered with water.
• Hence it becomes really slippery due to lack of friction while wood among the three options has highest friction and then comes the coir mat.
