An electron is launched at a 45 angle and a speed of 4.0x10 m/s from the positive plate of the parallel-plate shown. The electron lands 4.0 cm away. Assume that the electric force is the only force acting on the electron (aka. no gravity). a. What is the electric field strength inside the plates? (3) You will need both the charge and the mass of an electron, from the data provided in question 8. b. What is the smallest possible spacing between the plates? (1) 45 +++++++++++ 4.0 cm
