A chain of linear density 3 kg/m and length 8m is lying on the table with 4m of chain hanging from the edge. The work done in lifting the chain on the table will be....
Answers
The work done in lifting the chain on the table will 235.2 J
Explanation:
=> It is given that,
Linear density of chain = 3 kg/m
Length of the chain = 8 m
Unit length of hanging chain from the edge = 4 m
=> Mass of hanging chain, m:
m = linear density * unit length = 3 * 4 = 12 kg
=> Shift in centre of gravity on hanging chain, h:
h = d/2 = 4/2 = 2 m.
=> The work done in lifting the chain on the table:
w = mgh
= 12 * 9.8 * 2
= 235.2 J
Thus, the work done in lifting the chain on the table will 235.2 J
