Question

while measuring a 10cm long stick, 1 mistakably read its length 10.1cm.The percentage of error is.

Answer 1

Answer:

The percentage error = 1%

Step-by-step explanation:

Actual measurement = 10.1 cm

Correct measurement = 10 cm

Error in reading = Actual measurement - Correct measurement

∴ Error in reading = 10.1 - 10

∴ Error in reading = 0.1 cm

Percent error = (Error ÷ Correct measurement) ×100 %

∴ Percent error = (0.1 ÷ 10) × 100 %

∴ Percent error = 1%
