Measurement and Error

A : The maximum possible error in a reading is taken as least count of the measuring instrument. R : Error in a measurement cannot be greater than least count of the measuring instrument.

The percentage error in measurements of length and time period is 2% and 1% respectively . The percentage error in measurements of 'g' is
