Help with Part B
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 1.50 103 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 10-17 J. (Assume the potential energy at the point of release is zero.
Part A Answer is: 1.52e5 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 = 0.170 m, a change in potential energy of 4.57 10-17 J.
