A thin and uniform rod of mass M and length L is held vertical on a floor with large friction. The rod is released from rest so that it falls by rotating about its contact-point with the floor without slipping. Which of the following statement(s) is(are) correct, when the rod makes an angle 60° with vertical? [g is the acceleration due to gravity]

A

The radial acceleration of the rod's center of will be `(3g)/(4)`

B

The angular acceleration of the rod will be `(2g)/(L)`

C

The angular speed of the rod will be `sqrt((3g)/(2L))`

D

The normal reaction force from the floor on the rod will be `(Mg)/(16)`
