Question
Two beads A and B move along a semicircular wire frame as shown in figure. The beads are connected by an inelastic string which always remains tight. At an instant the speed of A is u, ⎳BAC = 45o and ⎳BOC = 75o where O is the centre of the semicircular arc. The speed of bead B at that instant is :
Options
A.√2 u
B.u
C.
D.
Solution
(A) u cos 45o = v cos 60o
or v = √2 u
or v = √2 uCreate a free account to view solution
