Q
Q: A student measures the length of a rod as 15.3 cm. If the true length is 15 cm, what is the error in measurement?
Solution:
Error in measurement = Measured value - True value = 15.3 - 15 = 0.3 cm.
Steps: 5
Show Steps
Step 1: Identify the measured value. In this case, the measured value is 15.3 cm.
Step 2: Identify the true value. Here, the true value is 15 cm.
Step 3: Subtract the true value from the measured value to find the error. So, calculate 15.3 cm - 15 cm.
Step 4: Perform the subtraction. 15.3 - 15 equals 0.3.
Step 5: State the error in measurement. The error is 0.3 cm.
