1.	Two particles each of mass m are attached at end points of a massless rod AB of length l. Rod is hinged at point C as shown. Rod is released from rest from horizontal position. At the instant when rod reaches its vertical position as shown, which of the following is / are correct:
Answer» Speed of the particle at B is thrice the speed of particle at A Net FORCE on particle B is `(6mg)/(5)` Angular acceleration of the SYSTEM is zero. Both x and y components of hinge force are non-zero Answer :A::B::C
