Question: “At what distance from the surface of the sphere is the electron’s speed half of its initial value?”
A 2.4 mm -diameter sphere is charged to -4.6 nC . An electron fired directly at the sphere from far away comes to within 0.30 mm of the surface of the target before being reflected. Part A: What was the electron’s initial speed? Express your answer in meters per second. Part B: At what distance from the surface of the sphere is the electron’s speed half of its initial value? Express your answer in meters. Part C: What is the acceleration of the electron at its turning point? Express your answer in meters per second squared.Answer: “At what distance from the surface of the sphere is the electron’s speed half of its initial value?”
