Torque and Angular Acceleration of a Rod
A uniform rod of mass M and length L is suspended horizontally by two vertical strings attached at distances L/4 and 3L/4 from its left end. The rod is initially in rotational equilibrium. If the string at the 3L/4 position breaks, what is the initial angular acceleration of the rod about its center of mass?
A
g/L
B
0
C
3g/2L
D
3g/L
