2. A wagon is sitting at the top of a hill that is 30m high. The wagon has a mass of
200 kg. The wagon has
energy. Calculate it.

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.)
