Question

A uniform chain of length 3m is kept on a table such that a length of 1m hangs freely from the edge of the table . The total mass of the chain is 4.5kg.
What is the work done in pulling the entire chain on the table.
Given that g= 10ms-²
plzz ans as fast as possible ​

Answer 1

Explanation:

Mass of the chain lying freely from the table=MLl

=4kg×20.6

=1.2kg

The distance of center of mass of chain from the table=21×0.6m=0.3m

Thus the work done in pulling the chain=mgh=1.2×10×0.3J=3.6J

Answer 2

Answer:

قع أمطرت فل ذات زالت البلاء
