I'm new to this, but the equation I have come up with is

v = √ 2QΔV

m

I then get this:

√ 2 x (1.602 x 10-19J) x (120-0 x 103eV) = √ 3.8448 x 10-14

8.2 x 10-14 J 8.2 x 10-14 J

√0.46887804 = 0.6847466977

To two significant figures and in scientific notation this is 6.8 x 10-1 eV s-1

I think I'm tying myself in knots - please help!
