what does it mean by closest approach? that's where i mainly got thrown off. and do i calculate the change in voltage and then calculate the change in energy? I am not sure what the question is asking by "closest approach" but my guess is something to do with voltage and energy

Homework Statement An alpha particle with kinetic energy 15.0MeVmakes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude L=p0b, where p0 is the magnitude...

ohhhh i feel stupid i did not see that part...thank you for the explanation though and pointing that out to me!

The question is A long metal cylinder with radius a is supported on an insulating stand on the axis of a long, hollow, metal tube with radius b. The positive charge per unit length on the inner cylinder is λ, and there is an equal negative charge per unit length on the outer cylinder...
