Let's solve the problem step by step based on the image you provided. This is a
triple beam balance used to measure mass in grams.

🔍 Understanding the Triple Beam Balance
A triple beam balance has three beams, each with a rider (sliding weight) that can be moved along a scale. The total mass is the sum of the values indicated by the riders on each beam.
The beams are labeled as:
-
Top beam: 0–100 g (in 10g increments)
-
Middle beam: 0–500 g (in 100g increments)
-
Bottom beam: 0–10 g (in 1g increments)
There’s also a
pointer and a magnified view on the right side showing the
balance point — the pointer should be centered for accurate measurement.

📏 Step-by-step Reading
We look at where each rider is positioned:
#### 1.
Top beam (0–100 g)
- Rider is at
40 g
#### 2.
Middle beam (0–500 g)
- Rider is at
500 g
#### 3.
Bottom beam (0–10 g)
- Rider is at
2 g
>
✔ So, total mass = 40 + 500 + 2 =
542 grams

🔎 Checking the Balance
- The
pointer is centered (as shown in the magnified view), which means the balance is level.
- The
object being weighed is placed on the left pan, and the
riders are adjusted on the right side until balanced.

🧩 What Object is Being Weighed?
On the left side of the balance, there is a
green cone on the pan.
Looking at the "Objects" panel:
- Paper clips
- Cone
- Light bulb
- Cube
✔ The object on the scale is the
Cone.
---
✔ Final Answer:
The
cone has a mass of
542 grams.

💡 Summary:
-
Mass measured: 542 g
-
Object: Cone
-
Balance is balanced, so reading is accurate.
