A dielectric equilateral triangle of dielectric constant 30 is inserted into uniform horizontal electric field of 100,000 N/C. What is the potential difference between two points 3 cm apart on one of the sides?
ΔV =∫E⋅dl E' =E/κ
The Attempt at a Solution
The electric field in the triangle is E/κ but I'm not sure along what path to integrate to find the potential difference.
