Question: The weight of an object is measured as 200 g with a possible error of 5 g. What is the range of the true weight?

Options:

  1. 195 g to 205 g
  2. 200 g to 205 g
  3. 195 g to 200 g
  4. 200 g to 210 g

Correct Answer: 195 g to 205 g

Solution: 

True weight range = Measured value ± Absolute error = 200 ± 5 = 195 g to 205 g.

The weight of an object is measured as 200 g with a possible error of 5 g. What

Questions & Step-by-Step Solutions

The weight of an object is measured as 200 g with a possible error of 5 g. What is the range of the true weight?
  • Step 1: Identify the measured weight of the object, which is 200 g.
  • Step 2: Identify the possible error in the measurement, which is 5 g.
  • Step 3: To find the range of the true weight, subtract the error from the measured weight: 200 g - 5 g = 195 g.
  • Step 4: Now, add the error to the measured weight: 200 g + 5 g = 205 g.
  • Step 5: The range of the true weight is from 195 g to 205 g.
