The engine provides a driving force of 5000N. One of the resistive forces has a magnitude of 3850N. Calculate the size of the second resistive force.

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.)
