An electron has a velocity of 3.2 x 10^6 m/s. what is its’ momentum? (b) what is its’ wavelength? (c) what other objects/materials have this space/size? (d) assuming that we can measure the velocity to an accuracy of 10%. use the heisenberg uncertainty principle to calculate the uncertainty in the position.

P = 2.91*10^{-24} kg m/s

size of atom hat lie in range of 1 to 5 Angstrom

Angstrom

Explanation:

A) MOMENTUM

p = mv

where m is mass of electron

so momentum p can be calculated as

p = 9.11*10^{-31} *3.2*10^{6}

P = 2.91*10^{-24} kg m/s

b) wavelength

where h is plank constant

so

c) size of atom hat lie in range of 1 to 5 Angstrom

d) from the information given in the question we have

we know that

Angstrom

answer: electrons
