An electron with a horizontal speed of 4.0 * 10^6 m/s and no vertical component of velocity passes through two horizontal parallel plates. The magnitude of the electric field between the plates is 150 n/c the plates are 6.0 long
A) calculate the vertical component of the electron's final velocity. (Ans 4.0 * 10^5)
B) calculate the final velocity of the electron. (Ana4.0 * 10^6)
