Two horizontal plates of opposite charge create a constant electric field
E, = 1000 N c directed vertically downwards (scc Figure). An clectron
of mass m, and charge -e is fired horizontally with velocity = 0.1c
between the plates. Calculate the clectron's acceleration; if the plates have
length lo = 1 m, find the clectron's deflection from the horizontal when it
cmerges. Neglect gravity in this calculation: is this justified?

- The following sequence of problems guides you through the calculation of the total electrie field at a target point in space when there are two source partieles. We'll stick to two dimensions (get rid of the z-axis) just to reduce some of the arithmetic. The source partieles are both located on the z-axis with source 1 at z = 5 em and source 2 at zz = -5 cm. Source 1 has charge -5 uC while source 2's charge is 3 µC. 2. First, calculate the electric field vector due to source I at the target location, (5,6) em.
