A long thin rod is cut into two pieces, one being twice as long as the other. To the midpoint of piece A (the longer piece), piece B is attached perpendicularly, in order to form the inverted "T" as shown in the figure. The application of a net external torque causes this object to rotate about axis 1 with an angular acceleration of `4.6"rad"//s^(2)`. When the same net external torque is used to cause the object to rotate about axis 2, what is the angular acceleration?

Options

A. `1.2"rad"//s^(2)`
B. `2.3"rad"//s^(2)`
C. `3.5"rad"//s^(2)`
D. `4.6"rad"//s^(2)`

Answer

B
