MCQ
Centre of mass of two thin uniform rods of same length but made up of different materials & kept as shown , can be, if the meeting point is the origin of co-ordinates
  • A
    $(L/2, L/2)$
  • B
    $(2L/3, L/2)$
  • C
    $(L/3, L/3)$
  • $(L/3, L/6)$

Answer

Correct option: D.
$(L/3, L/6)$
d
$CM$ of system line on $L$

$L_{1}\left(y-\frac{L}{2}\right)=\left(\frac{-L / 2}{L / 2}\right)(x-0)$

$y=-x+\frac{L}{2}$

$\because\left(\frac{L}{3}, \frac{L}{6}\right)$
