The figure below shows that the electric field through each of the five faces of a pyramid-shaped object is constant. The pyramid-shaped object in question has four triangular faces with equal area A and a base with area 1.2 A. The electric fields, E₁, E₂, E₃, E₄. and E₅ are perpendicular to the faces A₁, A₂, A₃, A₄, and A₅ respectively. Determine whether the pyramid object contains positive, negative, or zero charges and explain your answer using the concept of electric flux.
