A uniform triangular plate `ABC of` mass `m` and moment of inertia `I` (about an axis passing through `A` and perpendicular to plane of the plate) can rotate freely in the vertical plane about point `'A'` as shown in figure. The plate is released from the position shown in the figure. Line `AB` is horizontal. The acceleration of centre of mass just after the release of plate is

A

`("mga"^(2))/(sqrt(3I))`

B
