rod.

Answer 1

explain this quastion

Answer 2

I get the mass of the rod is at the 50 cm point. I get that the two knife edges are 10 cm from each of its ends. I read that a mass of 100 g is also 10 cm from one end (which is exactly on the knife edge). All this is leads to a question which you did not ask.
