Question 22: To weigh an object of mass 850g with a weighing box containing the following 12 weights: 1g, 2g, 2g, 5g, 10g, 20g, 20g, 50g, 100g, 200g, 200g, 500g, people use groups of fruits Which of the following is a weight?

Measuring the mass of an object with a Robovan balance is a way of comparing the mass of the object to be weighed with the mass of the sample weight.

Weigh an object with a mass of 850g using a Robovan balance, we will use a group of sample weights so that the total mass of the group of weights is 850g

A – 500g, 200g, 50g, 20g, 20g, 10g total 500 + 200 + 50 + 20 + 20 + 10 = 800g Wrong

B – 500g, 200g, 100g, 50g total 500 + 200 + 100 + 50 = 850g Yes

C – 500g, 100g, 100g, 50g total 500 + 100 + 100 + 50 = 750g Wrong

D – 500g, 100g, 50g, 10g total 500 + 100 + 50 + 10 = 660g Wrong

The answer to choose is: GET
