An electron is traveling with initial kinetic energy K in a uniform electric field. The electron comes to rest momentarily after
traveling a distance d. (a) What is the magnitude of the electric field
1 answer:
Answer:

Explanation:
Where E is the magnitude of electric field...
k is called Columb's Constant. It has a value of 8.99 x 109 N m2/C2.
Qs is the magnitude of the source charge...
and r is the magnitude of distance between source and target...
(When electron comes to rest Δt the magnitude of Electric field E become zero momentarily but later achieves the maximum value...)
