An `e^-` moving with a velocity of `2xx10^6m//s` . If the speed can be measured with an accuracy of 0.02%. Calculaate the uncertainty in its position is `1.45xx10^(-x)`. The value of x:

A golf ball has a mass of 40g and a speed of 45m//s . If the speed can be measured within accuracy of 2% , calculate the uncertainty in the position.

A ball has a mass of "10g" and speed of "20m/s" . If the speed can be measured with the accuracy of 1%, then the uncertainty in its position is

A golf has a mass of 40 g and a speed of 45 m s^(-1) .If the speed can be measured an accurary of 2% calculate the uncertainty in the position
