A chain lies on a rough horizontal table...

A chain lies on a rough horizontal table. It starts skidding when one fourth of it’s length hangs over the edge of the table. The coefficient of static friction between the chain and the surface of the table is

A

`1/2`

B

`1/3`

C

`1/4`

D

`1/5`

Text Solution

Verified by Experts

The correct Answer is:
B
Weight of the chain on table=`mg1/2mg=3/4mg`For maximum possible friction 3/4mumg=1/4mg"thereforemu=1/3`
