PRACTICE IT Use the worked example above to help you solve this problem. A proton is released from rest at x = -2.00 cm in a constant electric field with magnitude 1.50 x 103 N/C pointing in the positive x- direction. (a) Assuming an initial speed of zero, find the speed of a proton at x = 0.0600 m with a potential energy of -1.92 x 10-17 3.
(Assume the potential energy at the point of release is zero.) (1.51*10**5 m/s (b) An electron is now fired in the same direction from the same position. Find the initial speed of the electron (at x = -2.00 cm) given that its speed has fallen by half when it reaches x = 0.210 m, a change in potential energy of 5.53 x 10-17 ]. 1.27*10**7 m/s EXERCISE HINTS: GETTING STARTED | I’M STUCK! The electron in part (b) travels from x = 0.210 m (where it has half the initial speed you previously calculated) to x = -0.240 m within the constant electric field. If there’s a change in electric potential energy of -1.08 x 10-16 ) as it goes from x = 0.210 m to x = -0.240 m, find the electron’s speed at x = -0.240 m. (Note: Use the values from the Practice It section. Account for the fact that the electron may turn around during its travel.) Vx = x What factors will affect the velocity of the electron? How far has the electron moved in this instance? Through what field is it moving? m/s Need Help? Read It Talk to a Tutor
