20. ll How much work is required to completely separate two charges (each -1.4 micro C) and leave them at rest if they were initially 8.0 mm apart? 2.2 J
21. ll In Exercise 20, if the two charges are released at their initial separation distance, how much kinetic energy would each have when they are very distant from one another?
Homework Answers
As in question 20 the work is required to completely separate two charges (each -1.4 micro C) and leave them at rest if they were initially 8.0 mm apart is 2.2J
so,
At their initial separation distance the kinetic energy = work /2 = 2.2/2 =1.1 j
Answer : 1.1J
