Question
A thick uniform wire is bent into the shape of the letter “U” as shown. Which point indicates the location of the center of mass of this wire? A is the midpoint of the line joining mid points of two parallel sides of 'U' shaped wire.
Options
A.D
B.A
C.B
D.C
Solution
Sol.
$x_{cm} = \frac{m \times \frac{L}{9} - \frac{mL}{2}}{3m} = 0$
$y_{cm} = \frac{\frac{m\mathcal{l}}{2} + \frac{m\mathcal{l}}{2}}{3m}$
$y_{cm} = \frac{\mathcal{l}}{3}$
