Question # 1

Define systematic errors. Explain how can we remove the effect of systematic errors?

  • Ans 1: Systematic Errors: Systematic errors occurs when repeated measurements of a quantity give the same values under the same conditions.
    This error is due to poor calibration or zero error in the stop watch. This error can be removed by applying correction factor.
