Answer:

m = 500 grams

Explanation:

Assuming that the fulcrum is at the midpoint of a uniform meter stick, the moments about the fulcrum must be equal and opposite.

the 200 g mass makes a moment

200(g)[20] = 4000g gm•cm

the other mass must also create a moment of the same value

m(g)[8] = 4000g

m[8] = 4000

m = 500 grams
