In a measurement both positive and negative errors are found to occur with equal probablaity. The type of erros is

Positive And Negative Zero Error

(A) : Increasing the number of observations minimizes random errors. (R ) : Positive and negative random errors occur with equal probability.

If uncertainties in the measurement of position and momentum of an electron are found to be equal in magnitude, then what is the uncertainty in the measurement of velocity? Comment on the result.
