Answer :
Sure! Let's go through the question step-by-step to understand the precision of measurements that can be made using a triple beam balance.
1. Understanding the Instrument: A triple beam balance is used to measure mass. It typically has beams with sliding weights, which you adjust to find the mass of an object. The beam in this question is marked in increments of tenths of a gram.
2. Reading the Markings: When a beam is marked in increments of tenths of a gram, it means that the smallest division on the beam represents 0.1 gram. This is the smallest discrete amount that can be read directly from the balance.
3. Estimating Beyond the Marks: While the beam itself offers markings for tenths of a gram, skilled users can often estimate between these increments to a finer precision, but the markings themselves suggest the formal precision level.
4. Selecting the Precision Level: Given that each marking represents 0.1 gram, the balance allows us to measure to an exact tenth of a gram, but further estimations aren't directly indicated by the markings.
5. Conclusion: The correct answer is that the triple beam balance can measure to an estimated nearest tenth of a gram, which corresponds to option B.
So, the most precise measurement the balance can provide is to the nearest tenth of a gram.
