Question 84
Measurement made in Science lab must be as accurate as possible. Ravi measured the length of an iron rod and said, it was 19.34 cm long; Kamal said 19.25 cm; and Abish said 19.27 cm. the correct length was 19.33 cm. How much of error was made by each of the boys?
The actual length fo an iron rod = 19.33 cm
Measured Ravi = 19.34
Error= Measured value - Actual value
= (19.34- 19.33) cm = 0.01 cm
Kamal measured = 19.25 cm
Error = (19.25- 19.33) cm = - 0.08 cm.
Tabish measured = 19.27 cm
Error = (19.27- 19.3) cm = - 0.06 cm
