Question

If 10,000 alpha particles pass through the linear tube of radius per minute, what will be the resultant current?​

Answer 1

Answer:

Charge on one alpha particle is, q = 3.2 X 10^-19 C

So, total charge passing through the tube in 1 minute is = 10000 X 3.2 X 10^-19 C

=3.2 X 10^-15 C

Current = charge flow per second = (3.2 X 10^-15)/60 = 5.33 X 10^-17 A

Which is approximately, 0.5 X 10^-16 A
