There is a 100g mass sitting on the 10cm mark, and a 50g mass sitting on the 60cm mark. Force 𝐹 acts at the 30cm mark.

Answer 1

well I guess the meter stick? has mass M? down at 50 cm and F is upward at 30 balancing it all.
moments about zero
10 * 100 g + 50 * M g + 60 * 50 g = 30 * F
force up = weight down
F = 100 g + 50 g + M g
so
F = 150 g + M g
1000 g + 50 M g + 3000 g = 30 ( 150 g + M g)
4000 g + 50 M g = 4500 g + 30 M g
20 M g = 500 g
M = 25 grams mass of meter stick
F = 150 g + 25 g = 175 g up
