Of the quarks of the Standard Model, up, down, top, strange, charm, bottom. Which quark was the first one to be discovered, and which one was most recently discovered? PLEASE GIVE ME A DIRECT ANSWER! NO STRANGE LINKS WITH SKETCHY FILES
if you do I will report.

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
