A horizontal rod of mass M and length L ...

A horizontal rod of mass M and length L is tied to two verticle string symmetrically as shown in the figure. One of the strings at end Q is cut at `t=0` and the rod starts rotating about the other and P then

A

At `t=0`, angular acceleration of rod about `A` is `(3g)/(2L)`

B

At `t=0`, angular acceleration of rod about centre of mass of rod is `(3g)/(2L)`

C

At `t=0` , acceleration of centre of mass of rod is `(3g)/(4)` in downward direction

D

The tension in the other string through `A` at `t=0` is `(mg)/(4)` `(m` the mass of rod)
