Question
1) Figure 17.44 shows an electron passing between two charged metal plates that create an 100 N/C vertical electric field perpendicular to the electron's original horizontal velocity. (These can be used to change the electron's direction, such as in an oscilloscope.) The initial speed of the electron is 7.00 ? 106 m/s, and the horizontal distance it travels in the uniform field is 2.00 cm. (a) What is its vertical deflection? (b) What is the vertical component of its final velocity? (c) At what angle theta.gif does it exit? Neglect any edge effects.
2)An electron has an initial velocity of 5.00 ? 106 m/s in a uniform 2.00 ? 105 N/C strength electric field. The field accelerates the electron in the direction opposite to its initial velocity.
(a) What is the direction of the electric field?
(b) How far does the electron travel before coming to rest?
(c) How long does it take the electron to come to rest?
(d) What is the electron's speed when it returns to its starting point?
