Aboy drops a coin down a well that is 225 m deep. how long does it take the coin to hit the bottom of the well? ( state your final answer)

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.)
