Step 1
Given: Total length of the chain, \(L = 2m\) Length hanging from the edge of the table, \(l = 60cm = 0.6m\) Fraction hanging, \(n = \frac{l}{L} = \frac{0.6}{2} = \frac{3}{10} = \frac{1}{3}\) ** Show more…

A uniform chain of length $2 \mathrm{~m}$ is kept on a table such that a length of $60 \mathrm{~cm}$ hangs freely from the edge of the table. The total mass of the chain is $4 \mathrm{~kg}$. What is the work done in pulling the entire chain on the table? (A) $12 \mathrm{~J}$ (B) $3.6 \mathrm{~J}$ (C) $7.2 \mathrm{~J}$ (D) $1200 \mathrm{~J}$
