Question

2. What is the smallest mass you could measure with this balance beam?

Answer 1

From the given measure, let's find the smallest mass you could measure.

From the tape, we can see the third line has the smallest measure = 10 g

On the third measure, 1 line represents 0.2 g

Hence, the smallest mass you can measure is 2/10.

Therefore, we have:

`(2)/(10)=(1)/(5)`

Therefore, the smallest mass you could measure with balance beam is 1/5 g.

ANSWER:

`(1)/(5)\text{ g}`
