An electron has an uncertainty in its position of 603pm .
What is the uncertainty in its velocity?
Express your answer with the
appropriate units.
p x= h/4
mvx = h/4
v = h/4* mx
h=6.63 *10-34 m2 Kg sec-1 mass of electron (m) = 9.1*10-31 kg x = 603pm = 603 *10-12 m
v = h/4* mx
= 6.63 *10-34 m2 Kg sec-1 / 4 * 3.14 * 9.1*10-31 kg * 603*10-12 m
= 9.62 *104 msec-1
