Physics Lab #7-Electric Potential and Field NAME: Pre-lab questions: 1) S ketch the expected electric field patterns for equal and opposite charges separated by a distance d. Repeat for 2 infinite lines of equal and opposite charge separated by a d. How would you expect the electric field pattern to change of the lines have a finite length? (Hint: The line-line electrode arrangement should produce an electric field that is similar to a charged capacitor with a large plate separation.)...
