Question

A rod of very small diameter with a mass 2m and length 3L is placed along the xaxis with one end at the origin. An identical rod is placed along the yaxis with one end at the origin, so that the two rods form an L-shape. What are the coordinates of the center of mass for these two rods

Answer 1

coordinates of the center of mass for these two rods

(
`x_(cm)`,
`y_(cm)`)= (
`(3L)/(4)`,
`(3L)/(4)`)cm

Step-by-step explanation:

given

mass of a rod = 2m

length of the rod = 3L

mass of two rods = 2(2m) = 4m

radius = diameter/2 =
`(3L)/(2)`
