Homework Statement
A very long, thin straight line of charge has a constant charge density of 2.0 pC/cm. An electron is initially 1.0 cm from the line and moving away ( that is, perpendicular to the line ) with a speed of 1000 km/s. How far does the electron go before it comes back?
i can't seem to find the required equations in my textbook. any help would be great.
