Solve the following problems given below:
Problem 1: What is the shape of the equipotential curves very close to a conducting circular disk?
Problem 2: What is the shape of the field lines between two parallel conductors?
Problem 3: How do the lines of electric field alter, if a conducting circular disk is placed between the two conductors of question 2?
Problem 4: How do the lines of electric field alter, if an insulating circular disk is placed between the two conductors of question 2?
Any help I can get on these problems is greatly appreciated! I'm not too familiar with these problems.
