Question

calculate uncertainty in position of a bullet of mass 2g moving with a velocity of 300 meter per second

Answer 1

The uncertainity in position can be determined as follows:

dx . d(mv) = h /2π

dx is change in position

m is mass of bullet

h is plank constant

dx . (2 * 300) = (6.6 * 10^-34) / 2 * 3.14

dx (600) =  1.05 * 10^-34

dx = 1.75 * 10^-37 m

Thus, uncertainity in position of bullet is  1.75 * 10^-37 m
