A uniform metal rod is bent into L shape with the bent arms at

90^\circ

to each other. The distance of the centre of mass from the bent point is

View answer and explanation

Correct option: A

\frac{1}{{4\sqrt 2 }}

Option A (

\frac{1}{{4\sqrt 2 }}

) is correct because the center of mass of each arm is at L/2, and then the center of mass of the L shape is calculated considering the symmetry and equal masses.
