Physics question

[Rozan]

can someone guide me as to what formula should be used here?

hi!

i’ll take 1 token = 1 kg and 1 position = 1 m to simplifiy.
Sum of clockwise moments = Sum of counterclockwise moments
so F1d1=F2d2
m1gd1=m2gd2
m1d1=m2d2
m1d1=4 * 6 = 24
if we take 8 tokens and position 3:
8 * 3 = 4 * 6, this condition satisfies the equation

Hope this helps!
