APFIVE Net Torque and Angular Acceleration
A uniform solid disk of mass M and radius R is initially at rest on a frictionless horizontal surface. Three forces of equal magnitude F are applied tangentially to the disk’s edge as shown: one at the top, one at the bottom, and one at the right side. What is the resulting angular acceleration of the disk?
A
F·R/I, counterclockwise
B
Zero
C
F·R/I, clockwise
D
3F·R/I, clockwise
