Question

A uniform chain of mass 6 kg and length 10 m is placed on a frictionless horizontal table. Due to a small jerk, chain starts to slide down from edge of table. Find the speed of chain when chain is slips off completely. [Height of table is greater than 10m]

• A. 1 m/s
• B. 5 m/s
• C. 10 m/s
• D. 15 m/s

Answer 1

The correct option is C

10 m/s

$mg.\frac{1}{2}=\frac{1}{2}m{v}^2$ or $v=\sqrt{gl}$
