An experiment is performed to obtain the value of a physical property. If the true (i. e., correct) value of the property is 50 and the measured (i. e., experimental) value is 32, the percent error of the experimental result is:

36 %

Explanation:

Measured value = 32

Actual value = 50

Error can be caused due to multiple reasons operator error, equipment error and other environmental errors.

Error in the reading = |Actual value - Measured value|

= |50 - 32|

= |18| = 18

Percentage error = (Error / Actual value) * 100

= (18 / 50) * 100

= 0.36*100

= 36 %

∴ The percent error of the experimental result is 36 %.
