A 60kg student and a 1000N bear sit on a seesaw. The saw itself is 8m long with the pivot in the middle. The student sits on the end of the seesaw. Where must the bear sit in order to balance the system?

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.)
