The size of a microscopic particle is 1 micron and its mass is 6 xx 10^(-13)g. If its position may be measured to within 0.1% of its size, the uncertainity in velocity (in cm^(-1)) is approximately

The size of a microscopic particle is 1 micron and its mass is 6 xx 10

1.	The size of a microscopic particle is 1 micron and its mass is 6 xx 10^(-13)g. If its position may be measured to within 0.1% of its size, the uncertainity in velocity (in cm^(-1)) is approximately
Answer» `(10^(-7))/(4PI)` `(10^(-5))/(4pi)` `10^(-5)` `10^(-8)` Solution :`Delta X = (0.1)/(100) = 10^(-4) cm , Delta x . M Delta v ge (h)/(4pi)` `Delta V = h/(4pim) xx1/(Deltax) = (10^(-7))/(4pi)`
