1.	Table-tennis ball has a mass 10 g and a speed of 90 m/s. If speed can be measured within an accuracy of 4% what will be the uncertainty in speed and position
Answer» Solution :The Uncertainty in the speed of ball `=(90xx4)/(100)=(360)/(100)=(360)/(100)=3.6 MS^(-1)` Uncertainty in position = `(H)/(4pi m TRIANGLE V)`
