A) \[MgL\]
B) \[\frac{MgL}{3}\]
C) \[\frac{MgL}{9}\]
D) \[\frac{MgL}{18}\]
Correct Answer: D
Solution :
Since length of hanging part is\[\frac{L}{3}\], so its mass would be \[\frac{M}{3}\] and the weight \[\frac{Mg}{3}\] will act at the centre of gravity \[G\] of hanging part, which is at distance\[\frac{L}{6}\].You need to login to perform this action.
