Question
Using the symmetry of the arrangement, determine the direction of the force on q in the figure below, given that $q_a = q_b = +7.50\textrm{ }\mu\textrm{C}$ and $q_c=q_d = -7.50\textrm{ }\mu\textrm{C}$. (b) Calculate the magnitude of the force on the charge $q$ , given that the square is 10.0 cm on a side and $q = 2.00\textrm{ }\mu\textrm{C}$.
