Heisenberg uncertainty principle and measurement uncertainty: 2. (a) An electron is accelerated under an applied voltage of 8 V, assume the uncertainty of electron velocity is 1.5 % of its velocity. Calculate the uncertainty of electron position. What's the ratio of the electron position uncertainty to the electron diameter? (the classical electron radius is 2.818 x 10'> m) (b) A ball has a mass of 375 g, and diameter of 8.45 cm. Assume the ball has the same velocity as the electron. Calculate the uncertainty of ball's position. What's the ratio of the uncertainty of the ball's position to the diameter of the ball? (c) Based on your calculations, explain why electrons are well described as waves in this situation as opposed to the ball
