An electron moving at 20 km s- enters a uniform electric field of magnitude 500 V m- in the direction of its velocity. 21 a What is the kinetic energy of the electron? b Use an energy approach to calculate the distance it takes for the electron to come to a stop. c What is the potential difference between the initial point at which the electron entered the field and the point at which it comes to a stop?

Answer part g

part c is incorrect can you re do

part c please

Part a-c

part e only

5.a Please answer the following with a clear, readable and correct solution.

TACTICS BOX 1.1 Vector addition To add B to A (Figure 1), perform these steps: A 1. Draw A. A B 2. Place the tail of B at the tip of 3. Draw an arrow from the tail of A to the tip of B. This is vector A + B. 1- A+B ↑3 Create the vector R = A + B by following the steps in the Tactics Box above. When moving vector B, keep in mind that its direction should remain unchanged. Part A

Part E is the only part that I need help with to solve this problem

Part A-C
