प्रश्न
A student finds that the boiling point of water in a particular experiment is 97.8°C. If the actual boiling point of water is 99.4°C, calculate the percentage error.
उत्तर
Experimental value of boiling point of water = B.P1 = 97.8°C
Actual value of boiling point of water = B.P2 = 99.4°C
Absolute error = B.P2 – B.P1 = 99.4 – 97.8 = 1.6°C
Percentage error = `"Absolute error"/"Actual value"xx100`
= `1.6/99.4xx100`
= 1.60%
