Question
A ball of mass 1 kg is suspended by an inextensible string 1 m long attached to a point O of a smooth horizontal bar resting on a fixed smooth supports A and B. The ball is released from rest the position When the string makes an angle of 30o with the vertical. the mass of the bar is 4 kg The displacement In meter of the bar when the string makes the maximum angle on the on the other side the vertical
Options
A.0
B.0.2
C.0.25
D.0.5
Solution
ᐃ
= 
⇒
⇒ Displacement of bar = x = 0.2
= ⇒
⇒ Displacement of bar = x = 0.2
