Question

For a ball of mass 198.6 g to be located within 0.1 A, what will be the minimum uncertainty in velocity?
(1) 2.6 x 10-17 cm/s
(2) 2.6 x 10-18 m/s
(3) 2.6 x 10-21 cm/s
(4) 2.6 x 10-21 m/s


please do the method ​

Answer 1

Answer:

2.6 x10-21 cm/s

Explanation:

∆ו∆p>=h/4π

>= 6.626x10-34/0.1x10-10x

0.1986x4x3.14

>= 2.6 x 10-23 m/s

multiply by

>= 2.6 x 10-21 cm/s

Hope it helps
