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

coordinates of the center of mass for these two rods

(, )= (,  )cm

Explanation:

given

mass of a rod = 2m

length of the rod = 3L

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

radius = diameter/2 =

attached is the diagram and solution to the question

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

Are there options for this?
