Match the column 1  ( type of friction) with Column II ( value of  $\mu$) and select the correct answer from the codes given below .

	Column I		Column II
A	Static friction	1	$\mu$  is highest
B	Rolling friction	2	$\mu$  is moderate
C	Kinetic Friction	3	$\mu$  is lowest

A) Static friction is the frictional force between the surfaces of two objects when they are not in motion with respect to each other. Due to this reason, static friction has the highest value of frictional force and hence $\mu$ is highest.

B) Rolling friction takes place when one body rolls over the surface of another body due to which the value of friction is less in case of rolling friction and hence $\mu$ is lowest.

C)  kinetic friction takes place when one body slides over the surface of the another body. Value of friction is moderate and lie in between the friction values of rolling and static friction and hence $\mu$  is moderate.

 Hence ,  $A\to 1,B\to 3andC\to 2.$
