1. The problem statement, all variables and given/known data in the following figure, the dashed line denotes a Gaussian surface enclosing part of a distribution of four positive charges. a) which charges contribute to the electric field at P? b) is the value of the flux though the surface, calculated using only the electric field due to q1 and q2, greater than, equal to, or less than that obtained using the field due to all four charges? 2. Relevant equations Φ=∫E*A=Q<sub>enclosed/ε Φ=∫E*A=Qenclosed/ε 3. The attempt at a solution a)what I tried to do is to draw the field line of each charge since all of them are positive they will repel each other and at P the electric field will be zero so none of them contributes to the field b) I dont fully understan question B but I would say that since all charges are equal and for the flux through the surface I will only consider q1 and q2 the flux must be equal hel please!
