Rotational MotionHard
Question
A light rod carries three equal masses A, B and C as shown in figure.
What will be velocity of B in vertical position of rod, if it is released from horizontal position as shown in figure?
What will be velocity of B in vertical position of rod, if it is released from horizontal position as shown in figure?
Options
A.
B.
C.
D.
Solution
Loss in P. E. = Gain in K. E. mg 
+ mg 
= 
⇒ ω =
+ mg = ⇒ ω =
