A horizontal plank with a frictionless axis of rotation at its center has a large mass at one end and a small mass at the other end. It is held stationary and then released. As the plank rotates and before one end hits the ground), the magnitude of the net torque on the plank about the center (increases/decreases/or remains constant) and the magnitude of the angular acceleration (increases/decreases/or remains constant)?
A) te increases and a decreases
B) t decreases and all increases
C) t remains constant and a decreases
D) t decreases and a decreases
E) t remains constant and a remains constant
