Homework Statement Just going over some practice questions, and one of them is: 1. Verify the value of the constant, 1240, in the Duane-Hunt relation. Homework Equations E(eV) = 1240/lambda(nm) The Attempt at a Solution I know it is used as a quick method in finding how much...

Thank you again gneill. I have now arrived at the same answer as the OP. I was a little confused with the quadrants but I figured it out.

the direction would be to the left towards the charge, right?

oh okay! simple enough. thanks a bunch.

do I multiply the test charge with 6.242 × 10^18 e using millikan's relationship?

1.60217646 × 10-19

For this very same question above, how would I determine the electrons that were gained or lost from the test subject to create the charge?

Thanks gneill, I just seem to be lost and/or over thinking this. I know the direction caused by the repulsive force of q3 is up. For q2 I broke it up into it's x and y components as you suggested (converting the cm lengths to meters): x-component: -(2.7 x 10^-23)(0.4/0.5) = -2.6 x 10^-23...

I'm working on this same problem. I've calculated individual force that q2 and q3 are inflicting on q1, and I've calculated the angles of A, B, and C of the triangle. I know I now have to use trig: 2F = force of q2 on q1 3F = force of q3 on q1 Fnet^2 = (2F)^2 + (3F)^3 - 2(2F)(3F)cos(126.9...
