Consider an electron with a mass of 9.11 x 1051 kg and a 100.0 g tennis ball that are both moving with a velocity of 70.0 m s1. (a) calculate the momentum of the electron (p mv). (b) calculate the momentum of the tennis ball (c) what is the uncertainty in the position of the electron (ax) if the uncertainty in its momentum (ap) is equal to 1.0 % of p for the electron? (d) what is the uncertainty in the position of the tennis ball (ax) if the uncertainty in momentum (ap) is equal to 0.1% of p for the tennis ball? (e) comment on how the uncertainty in position (ax) compares to the overall size in each case
