Title: The drawing shows a square, each side of which has a length of . On two corners of the square are fixed different positive charge . Find the electric potential energy of a third charge placed at corner A and then at corner B.
Description: It seems like there is some information missing in your description, specifically the length of the square's sides and the magnitudes of the positive charges at the two corners. In order to calculate the electric potential energy of a third charge at corners A and B, I would need these missing values. However, I can provide you with the general formula to calculate the electric potential energy between point charges. The electric potential energy � U between two point charges � 1 q 1 ​ and � 2 q 2 ​ separated by a distance � r can be calculated using Coulomb's law: � = � ⋅ � 1 ⋅ � 2 � U= r k⋅q 1 ​ ⋅q 2 ​ ​ Where: � k is Coulomb's constant ( � = 8.9875 × 1 0 9   N ⋅ m 2 / C 2 k=8.9875×10 9 N⋅m 2 /C 2 in SI units) � 1 q 1 ​ and � 2 q 2 ​ are the magnitudes of the charges � r is the distance between the charges To calculate the total electric potential energy when you have multiple charges, you would sum up the contributions from each pair of charges in the system. Once you provide the missing values, I can help you calculate the electric potential energy for the third charge placed at corners A and B of the square.
