Calculating Current of Alpha Particle Beam

[Jabababa]

Homework Statement

If a beam of 9.39 x10^20 alpha particles passes a given point in 1.50s, what is the current?

Homework Equations

I=q/t

The Attempt at a Solution

umm the answer is 2.00 x 10^2 A, not sure where to begin. Would be a great help if someone can point me to the right direction.

Just apply the equation you wrote in section 2.

umm can you show me? I don't see how that can come out to be 2.00 x 10^2 A.

What's the charge on an alpha particle?
Then you can work out the total charge passing the point in the 1.50s interval.
Then just apply the equation.

The charge of an alpha particle is +2.
How do i find the total charge? Because i don't know how to incorporate the 9.39 x10^20 part of the question into the equation.

Charge is measured in Coulombs when using the standard equations !

The charge on one alpha particle is 2e
What's the charge on x alpha particles?

woot, thank you! I got it.
