A particle with mass m = 1.20g and charge q = 345ìC is traveling in the x-direction with an initial velocity of v0 = 68.0m/s. The particle passes through a constant electric field in the y-direction with magnitude |E| = 263N/C over a distance of d = 12.0m. (a) What is the magnitude of the velocity after exiting the constant electric field? (b) What angle does the trajectory of the particle make with the horizontal after the particle exits the constant electric field?
