A beam of electrons is shot into a uniform downward electric fieldof magnitude 1.11 103 N/C. The electrons have an initial velocityof 1.05 107 m/s, directed horizontally. The field acts over a smallregion, 5.00 cm in the horizontal direction.
(a) Find the magnitude and direction of the electric force exertedon each electron.
I know the direction is upward, but I don't know how to calculatethe magnitude.
(b) How does the gravitational force on an electron compare withthe electric force?
I know the answer to B is The gravitational force is much smallerthan the electric force.
(C)How far has each electron moved in the vertical direction by thetime it has emerged from the field?
(d) What is the electron's vertical component of velocity as itemerges from the field? (Up is the positive y-direction.
(e) The electrons move an additional 20.6 cm after leaving thefield. Find the total vertical distance that they have beendeflected by the field.
Please when you answer these questions please tell me the formulaand how you did each problem step by step. No matter what I do, I'mgetting the answer wrong.
