Question

An electron has an initial velocity of 2×10⁶ m/s in the +x direction. It enters a uniform electric field E = 388 N/C which is in the +y direction. By how much, and in what direction, is the electron deflected after traveling 11 cm in the +x direction in the field? (Express the direction of deflexion by using positive and negative signs. Your result must be in cm's and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take elementary charge 1.6x10^-19 C and mass of electron 9.1x10^-31 kg.)

Answer 1

Here we apply definition of electric force and concept of kinematics and equation of motion for constant acceleration.
