What is the mass, in grams, of the object being measured in the triple beam balance shown below? a) 5.5 g b) 25.5 g c) 50.5 g d) 100.5 g

Reading will be

m = 25.5 g

Explanation:

As we know that here the scale is divided into three parts

total reading is the sum of reading due to each part

here from first scale the reading is given as

from second scale the reading will be

from third scale the reading will be

so total reading will be

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
